FEATURES

DESCRIPTION

Also known as SRC8_MOUSE, Cttn, Ems1. Contributes to the organization of the actin cytoskeleton and cell shape (PubMed:17403031). Plays a role in the formation of lamellipodia and in cell migration (By similarity). Plays a role in the regulation of neuron morphology, axon growth and formation of neuronal growth cones (By similarity). Through its interaction with CTTNBP2, involved in the regulation of neuronal spine density (PubMed:22262902). Plays a role in the invasiveness of cancer cells, and the formation of metastases (By similarity). Plays a role in focal adhesion assembly and turnover (By similarity). In complex with ABL1 and MYLK regulates cortical actin-based cytoskeletal rearrangement critical to sphingosine 1-phosphate (S1P)-mediated endothelial cell (EC) barrier enhancement (By similarity). Plays a role in intracellular protein transport and endocytosis, and in modulating the levels of potassium channels present at the cell membrane (PubMed:17959782). Plays a role in receptor-mediated endocytosis via clathrin-coated pits (By similarity). Required for stabilization of KCNH1 channels at the cell membrane (By similarity). Interacts with SHANK2 and SHANK3 (via its SH3 domain). Interacts with PLXDC2 and SRCIN1. Interacts with SAMSN1 (via SH3 domain). Interacts (via SH3 domain) with ASAP1 (via Pro-rich region). Interacts (via SH3 domain) with DNM2. Interacts with ACTN1 (By similarity). Interacts with FER. Forms a complex with ABL1 and MYLK (By similarity). Interacts with KCNA2 (via non-phosphorylated C-terminus). Interacts with FGD1. Identified in a complex containing FGFR4, NCAM1, CDH2, PLCG1, FRS2, SRC, SHC1, GAP43 and CTTN. Interacts with ABL2 (PubMed:22297987). Interacts with CTTNBP2NL; this interaction may target CTTN to stress fibers. Interacts with CTTNBP2; this interaction may target CTTN at the cell cortex or dendritic spines. Interacts with KCNH1 (By similarity). Interacts (via SH3 domain) with DIP2A (via N-terminus); the interaction enhances CTTN acetylation and is required for proper synaptic transmission (PubMed:31600191).
