The posttranslational regulation of the neuronal proteome is critical for brain homeostasis but becomes dysregulated in the aged or diseased brain, in which abnormal posttranslational modifications (PTMs) are frequently observed. While the full extent of modified substrates that comprise the "PTM-ome" are slowly emerging, how the upstream enzymes catalyzing these processes are regulated themselves is not well understood, particularly in the context of neurodegeneration. Here, we describe the reciprocal regulation of a kinase, the microtubule affinity-regulating kinase 2 (MARK2), and an acetyltransferase, CREB-binding protein (CBP), two enzymes known to extensively modify tau proteins in the progression of Alzheimer's disease. We found that MARK2 negatively regulates CBP and, conversely, CBP directly acetylates and inhibits MARK2 kinase activity. These findings highlight a reciprocal negative feedback loop between a kinase and an acetyltransferase, which has implications for how PTM interplay is coordinated on substrates including tau. Our study suggests that PTM profiles occur through the posttranslational control of the master PTM remodeling enzymes themselves.
神经元蛋白质组的翻译后调控对大脑的平衡至关重要，但在衰老或患病的大脑中却会出现失调，在这种情况下经常会观察到异常的翻译后修饰（PTM）。虽然构成 "PTM-ome "的全部修饰底物正在慢慢浮出水面，但人们对催化这些过程的上游酶本身是如何调控的还不甚了解，尤其是在神经变性的背景下。在这里，我们描述了一种激酶--微管亲和性调节激酶 2（MARK2）和一种乙酰转移酶--CREB 结合蛋白（CBP）--的相互调控，这两种酶已知在阿尔茨海默病的进展过程中广泛修饰 tau 蛋白。我们发现 MARK2 负向调节 CBP，反之，CBP 直接乙酰化并抑制 MARK2 激酶的活性。这些发现强调了激酶和乙酰转移酶之间的相互负反馈循环，这对如何协调包括 tau 在内的底物上的 PTM 相互作用具有重要意义。我们的研究表明，PTM 特征是通过主 PTM 重塑酶本身的翻译后控制发生的。

Of the 12 specimens of Calathus-like sphodrine beetles presently known from Baltic and Rovno amber deposits, 11 specimens were investigated using light microscopy, micro-CT scanning, and 3D imaging techniques. For the first time, many significant diagnostic characters of the external morphology and male and female genitalia of Eocene Sphodrini were studied in detail. Based on these data, three fossil species are diagnosed and placed in a natural group characterized by a derived pattern in elytral chaetotaxy and microsculpture and therefore the genus Quasicalathus Schmidt & Will, gen. nov. is described to comprise these species. Due to the presence of a styloid right paramere, Quasicalathus gen. nov. is considered a member of the sphodrine “P clade” of Ruiz et al. (2009). However, given the absence of synapomorphies of any species group of the P clade, the systematic position of Quasicalathus gen. nov. within this clade remains unresolved. The Baltic amber species Calathus elpis Ortuño & Arillo, 2009 is redescribed based on additional, fossil, non-holotype material and transferred to Quasicalathus gen. nov. Identification of the additional C. elpis fossil material remains slightly uncertain due to the non-availability of the holotype for direct comparison coupled with doubts regarding the accuracy of certain character states presented in its original description. Two species are newly described: Quasicalathus agonicollis Schmidt & Will, sp. nov., from Baltic amber, and Q. conservans Schmidt & Will, sp. nov., from Rovno amber.

In spite of big data and new techniques, the phylogeny and timing of cockroaches remain in dispute. Apart from sequencing more species, an alternative way to improve the phylogenetic inference and time estimation is to improve the quality of data, calibrations and analytical procedure. This study emphasizes the completeness of data, the reliability of genes (judged via alignment ambiguity and substitution saturation), and the justification for fossil calibrations. Based on published mitochondrial genomes, the Bayesian phylogeny of cockroaches and termites is recovered as: Corydiinae + (((Cryptocercidae + Isoptera) + ((Anaplectidae + Lamproblattidae) + (Tryonicidae + Blattidae))) + (Pseudophyllodromiinae + (Ectobiinae + (Blattellinae + Blaberidae)))). With two fossil calibrations, namely, Valditermes brenanae and Piniblattella yixianensis, this study dates the crown Dictyoptera to early Jurassic, and crown Blattodea to middle Jurassic. Using the ambiguous ‘roachoid’ fossils to calibrate Dictyoptera+sister pushes these times back to Permian and Triassic. This study also shows that appropriate fossil calibrations are rarer than considered in previous studies.

Ornatoraphidia flavilabris (Costa, 1851) is one of 15 snakefly species occurring in southern parts of Central Europe. It is a polycentric Mediterranean faunal element with refugia in the Apennine Peninsula and the Balkan Peninsula. Two phylogeographic questions are dealt with in this paper: (1) Is it possible to differentiate, morphologically or genetically, the Balkanic populations from the Italian? (2) Did the species reach Central Europe from the Balkan or Apennine Peninsula? These questions were investigated using morphological and molecular biological methods. No morphological characters were uncovered which could serve to differentiate specimens from either distribution center. However, differences were detected in cox1, cox3 and 28S genes which allow for a reliable differentiation. Central European populations were largely identical with populations from Italy, but distinctly different from specimens from Greece. This could lead one to assume that the species migrated from Italy to Central Europe, although colonization from the southeast would appear easier due to more favorable orographic conditions. This discrepancy may be explained by the apparent absence of O. flavilabris from the large central part of the Balkan Peninsula, so that a gap exists between the southern and northern areas inhabited by O. flavilabris. Moreover, the species does not occur in eastern parts of Europe. Thus it would be more probable to assume that the occurrence of the species in the northwest Balkan Peninsula can be traced to migrations from the Apennine Peninsula to areas north and northeast of the Adriatic Sea, where O. flavilabris may have colonized the southeast of Central Europe. A migration of Adriatomediterranean faunal elements from the northwest Balkan Peninsula to Central Europe might be of more significance than previously assumed.

The first instar nymphs of two peltoperlid stoneflies, i.e., Microperla brevicauda Kawai, 1958 of Microperlinae and Yoraperla uenoi (Kohno, 1946) of Peltoperlinae, were examined and described. Additionally, the phylogeny and groundplan of the first instar nymphs of Peltoperlidae and Plecoptera were considered. The first instar nymphs of M. brevicauda have a slender body with a prognathous head of typical shape; they represent a groundplan in Plecoptera. On the other hand, the first instar nymphs of Y. uenoi have a broad, cockroach-like body with an orthognathous and shortened head, the latter being regarded as a potential autapomorphy of Peltoperlinae. Such differences in body shape between the subfamilies are speculated to arise from heterochrony. The three-segmented cerci of Y. uenoi are characteristic to Systellognatha, whereas the four-segmented cerci of M. brevicauda were independently acquired within Microperlinae. The structure and distribution pattern of chloride cells in the first instar nymphs of Plecoptera were also discussed. The presence of coniform chloride cells is a potential groundplan of Arctoperlaria. One to two pairs of chloride cells are distributed on the first nine abdominal segments of M. brevicauda; this represents a groundplan character of Systellognatha. On the other hand, one to four pairs of chloride cells are found on the second to ninth abdominal segments of Y. uenoi; this distribution pattern may be an apomorphic groundplan of Peltoperlinae.

On the other hand, one to four pairs of chloride cells are found on the second to ninth abdominal segments of Y. uenoi; this distribution pattern may be an apomorphic groundplan of Peltoperlinae.","PeriodicalId":50592,"journal":{"name":"Deutsche Entomologische Zeitschrift","volume":"68 1","pages":"179-188"},"PeriodicalIF":0.8,"publicationDate":"2021-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44028881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
