Sqstm1/p62 (named a170 in the mouse;hereafter p62) is the first proposed example of such proteins (bj_?_?Rk_?_?Y et al.,2005). It binds polyubiquitinated protein aggregates via its uba domain and interacts with lc3 on the autophagosome/ this interaction is necessary for autophagic degradation of p62-positive cytoplasmic inclusion bodies containing ubiquitinated proteins. We also demonstrate that alis are indistinguishable from p62 inclusion bodies and that p62 is required for their formation.

To better understand the role of the egfr tyrosine kinase, we analyzed signaling by a kinase-inactive egfr (k721m) in erbb-devoid 32d cells. K721m alone exhibited no detectable signaling capacity, whereas coexpression of k721m with erbb2, but not erbb3 or erbb4, resulted in egf-dependent mitogen-activated protein kinase (mapk) activation. The kinase activity, but not tyrosine phosphorylation, of erbb2 was required for egf-induced mapk activation.

We demonstrate that ERK, JNK, and p38 are activated by distinct combinations of stimuli in T cells that simulate full or partial activation through the T cell receptor. These kinases are regulated by reversible phosphorylation on Tyr and Thr, and the dual specific phosphatases PAC1 and MKP-1 previously have been implicated in the in vivo inactivation of ERK or of ERK and JNK, respectively

Rho kinase is known to control smooth muscle contractility by phosphorylating the 110 kDa myosin-targetting subunit (MYPT1) of the myosin-associated form of protein phosphatase 1 (PP1M). Phosphorylation of MYPT1 at Thr695 has previously been reported to inhibit the catalytic activity of PP1. Here, we show that the phosphorylation of Thr850 by Rho kinase dissociates PP1M from myosin, providing a second mechanism by which myosin phosphatase activity is inhibited.

We find that the small GTPase Rho regulates R-cadherin adherens junction formation via Dia1 (also known as p140mDia) and profilin-1-mediated signaling pathway. The role played by Rho in regulating R-cadherin is underscored by the fact that constitutively active RhoA(Q63L) induces R-cadherin junction formation in MDA-MB-231 cells.|Data presented thus far demonstrated that Rho, Dia1, and profilin-1 were required for R-cadherin junction formation in N480 cells.

We demonstrate that mrn and atr/atr-interacting protein (trip) interact with each other, and the forkhead-associated/breast cancer c-terminal domains (fha/brct) of nbs1 play a significant role in mediating this interaction. Mutations in the fha/brct domains do not prevent atr activation but specifically impair atr-mediated nbs1 phosphorylation at ser-343, which results in a defect in the s-phase checkpoint.

Three of them (S80, S82, and S473) were also phosphorylated in vitro by CKI and are conserved between axin1 and axin2/conductin.|This suggests that cumulative phosphorylation of axin is required for it to fully downregulate Wnt/beta_catenin signaling.

Kindlin-2-Y193 phosphorylation is also involved in its binding capacity with Migfilin and the recruitment of Migfilin to the focal adhesions. Functionally, we demonstrate that Kindlin-2-Y193 phosphorylation regulates Kindlin-2-mediated cell spreading and migration.

BCKD is inhibited by phosphorylation of its E1alpha subunit at Ser293, which is catalyzed by BCKD kinase. During BCAA excess, phosphorylated Ser293 (pSer293) becomes dephosphorylated through the concerted inhibition of BCKD kinase and the activity of an unknown intramitochondrial phosphatase. Using unbiased, proteomic approaches, we have found that a mitochondrial-targeted phosphatase, PP2Cm, specifically binds the BCKD complex and induces dephosphorylation of Ser293 in the presence of BCKD substrates

Binding to MTs correlates with the unfolding of CLIP-170, which allows the interaction of the COOH-terminal domain with its binding partners, such as dynactin, resulting in their recruitment to the MT tip. The NH2 terminus of p150Glued binds directly to the COOH terminus of CLIP-170 through its second metal-binding motif.
