产品介绍  :  This gene is overexpressed in breast cancer and squamous cell carcinomas of the head and neck. The encoded protein is localized in the cytoplasm and in areas of the cell-substratum contacts. This gene has two roles: (1) regulating the interactions between components of adherens-type junctions and (2) organizing the cytoskeleton and cell adhesion structures of epithelia and carcinoma cells. During apoptosis, the encoded protein is degraded in a caspase-dependent manner. The aberrant regulation of this gene contributes to tumor cell invasion and metastasis. Three splice variants that encode different isoforms have been identified for this gene. [provided by RefSeq].

Function:

Contributes to the organization of the actin cytoskeleton and cell structure. Plays a role in the regulation of cell migration. Plays a role in the invasiveness of cancer cells, and the formation of metastases.

Subunit:

Interacts with SHANK2 and SHANK3 (via its SH3 domain). Also interacts with FGD1. Identified in a complex containing FGFR4, NCAM1, CDH2, PLCG1, FRS2, SRC, SHC1, GAP43 and CTTN. Interacts with ABL2 (By similarity). Interacts with PLXDC2 and SRCIN1. Interacts with SAMSN1 (via SH3 domain). Interacts (via SH3 domain) with ASAP1 (via Pro-rich region). Interacts with DNM2 and FER. Binds to MYLK. A complex made of ABL1, CTTN and MYLK regulates cortical actin-based cytoskeletal rearrangement critical to sphingosine 1-phosphate (S1P)-mediated endothelial cell (EC) barrier enhancement.

Subcellular Location:

Cytoplasm, cytoskeleton. Cell projection, lamellipodium. Cell projection, ruffle. Note=Associated with membrane ruffles and lamellipodia.

Post-translational modifications:

Phosphorylated by PKN2 at both serine and threonine residues in a GTP-bound Rac1-dependent manner in hyaluronan-induced astrocytes and hence down-regulated CTTN ability to associates with filamentous actin (By similarity). Phosphorylated by FER. Tyrosine phosphorylation in transformed cells may contribute to cellular growth regulation and transformation. Phosphorylated in response to FGR activation. Phosphorylation by SRC promotes MYLK binding.

Similarity:

Contains 7 cortactin repeats.

Contains 1 SH3 domain.
