| Short Name | Nck1_SH3_2 |
| description | This entry represent the second SH3 domain of Nck1. The second SH3 domain of Nck appears to prefer ligands containing the APxxPxR motif [].Nck1 (also called Nck-alpha) plays a crucial role in connecting signaling pathways of tyrosine kinase receptors and important effectors in actin dynamics and cytoskeletal remodeling []. It binds and activates RasGAP, resulting in the downregulation of Ras []. It is also involved in the signaling of endothilin-mediated inhibition of cell migration [].Cytoplasmic proteins Nck are non-enzymatic adaptor proteins composed of three SH3 (Src homology 3) domains and a C-terminal SH2 domain []. They regulate actin cytoskeleton dynamics by linking proline-rich effector molecules to protein tyrosine kinases and phosphorylated signaling intermediates []. They function downstream of the PDGFbeta receptor and are involved in Rho GTPase signaling and actin dynamics []. They associate with tyrosine-phosphorylated growth factor receptors or their cellular substrates [, ]. There are two vertebrate Nck proteins, Nck1 and Nck2. |
