Polyclonal Antibody to ASAP2

ASAP2 (Arf-GAP with SH3 domain, ANK repeat and PH domain-containing protein 2) or Development and differentiation-enhancing factor 2 (DDEF2) or Paxillin-associated protein with ARF GAP activity 3 (PAG3) is a multidomain protein containing two ANK repeats, one Arf-GAP domain, one PH domain and one SH3 domain. ASAP2 has two isoforms: PAPalpha and PAPbeta (111 and 106 kDa respectively) and both the isoforms are generally located in Golgi plasma membrane, where it colocalizes with protein tyrosine kinase 2-beta (PYK2) . ASAP2 regulates ARF-mediated vesicle budding when vesicular transport. ASAP2 has high level of expression in brain, kidney, and heart.
