Protein Function ABRACL modulates actin dynamics through its interaction with cofilin and thereby regulates cancer cell migration and participates in cancer pathogenesis.
Biochemical Properties Although ABRACL resembles the F-actin-binding domain of ABRA, it has further defined two F-actin-binding domains, ABD1 (aa 193–296) and ABD2 (aa 294–375); both domains can bind F-actin independently when tested in vitro, but ABD2 binds with a much lower affinity than ABD1. The protein sequence of ABRACL exhibits homology mostly to ABD2, with ~40% identities and ~60% similarities to aa 326–381 of ABRA.

Additional Comments ABRACL is overexpressed in cancerous tissues and that cancer cells with ABRACL expression, rather than cells depleted of ABRACL, migrate more robustly, proliferate better, and are more capable of generating colonies even under anchorage-independent conditions.
