This domain family is found in eukaryotes, and is approximately 120 amino acids in length. The family is found in association with Pfam:PF01412, Pfam:PF00023, Pfam:PF08518. GIT1 plays an important role in cell adhesion, motility, cytoskeletal remodelling and membrane trafficking. To perform this function, it localises p21-activated kinase (PAK) and PAK-interactive exchange factor to focal adhesions. Its activation is regulated by interaction between its paxillin-binding C terminal and the LD motifs of paxillin. The C terminal folds into a four helix bundle.	Domain
