Here we show that KATNAL2 is critical for numerous aspects of this developmental process, including the initiation of the axoneme from the basal body, suppression of the spermatid centriole duplication cycle, sperm nuclear sculpting via the manchette, the attachment of the acrosome to the nucleus and the tethering of elongated spermatids to Sertoli cells via the tubulobulbar complex and ultimately sperm release via spermiation. KATNAL2 does not sever microtubules composed of α- and β-tubulin but does interact with δ- and ε-tubulin

TGF-beta represses transcription of pulmonary surfactant protein-B gene in lung epithelial cells. Repression is mediated by SMAD3 through interactions with NKX2.1 and FOXA1, two key transcription factors that are positive regulators of SpB transcription. In this study, we found that SMAD3 interacts through its MAD domains, MH1 and MH2 with NKX2.1 and FOXA1 proteins. The sites of interaction on NKX2.1 are located within the NH2 and COOH domains, known to be involved in transactivation function.

In response to ionizing radiation (ir), atm, the gene product mutated in ataxia telangiectasia, stabilizes and activates p53 through phosphorylation of ser15 and (indirectly) ser20. Here we show that phosphorylation of p53 on ser46, a residue important for p53 apoptotic activity, as well as on ser9, in response to ir also is dependent on the atm protein kinase. one pathway involves the phosphorylation of p53 and its negative regulator mdm2 by ataxia telangiectasia mutated (atm) and chk2 causing p53 activation and stabilization.

The mammalian tachykinins include substance p, neurokinin a and neurokinin b, which exert their effects by binding to specific receptors. These tachykinin receptors are divided into three types, designated nk1, nk2 and nk3, respectively. The interaction of tachykinin with its receptor activates gq, which in turn activates phospholipase c to break down phosphatidyl inositol bisphosphate into inositol trisphosphate (ip3) and diacylglycerol (dag).

In addition, we identify 14-3-3epsilon as an NR2C interactor, whose binding is dependent on S1096 phosphorylation. These data are all consistent with a model in which NR1 and NR2C oligomerize, PKB phosphorylates S1096, and 14-3-3ε binds to phosphorylated NR2C thereby promoting NR2C-containing NMDA receptor surface expression in cerebellar granule cells.

The abundance of histone H2A, H2B, H3, and H4 mRNAs is reduced to 37% to 70% of control levels in the SLBP knockdown cells when compared to the C2 control.

To address whether PP1\u03b1 activates B-Raf through these inhibitory sites, we made use of B-Raf protein mutants in which an individual inhibitory site, as well as all four sites (4A), were mutated to alanine.|We confirmed that GST-B-Raf was phosphorylated by ERK2 in vitro xref , mainly on S151 and T753 (Fig.\u00a0 xref ), and found that PP1\u03b1 dephosphorylated B-Raf on both ERK phosphorylation sites (Fig.\u00a0 xref ).

Collectively, this is the first report to show that STC2 was aberrantly hypermethylated in human cancer cells. The findings demonstrated that STC2 epigenetic inactivation may interfere with HIF-1 mediated activation of STC2 expression.
