Anti-alpha Adaptin/AP2A1 Antibody Picoband® Fluoro550 Conjugated

AP-2 complex subunit alpha-1 is a protein that in humans is encoded by the AP2A1 gene. This gene encodes the alpha 1 adaptin subunit of the adaptor protein 2 (AP-2) complex found in clathrin coated vesicles. The AP-2 complex is a heterotetramer consisting of two large adaptins (alpha or beta), a medium adaptin (mu), and a small adaptin (sigma) . The complex is part of the protein coat on the cytoplasmic face of coated vesicles which links clathrin to receptors in vesicles. Alternative splicing of this gene results in two transcript variants encoding two different isoforms. A third transcript variant has been described, but its full length nature has not been determined.

Protein phosphatase 1E; Ca (2+) /calmodulin-dependent protein kinase phosphatase N; CaMKP-N; CaMKP-nucleus; CaMKN; Partner of PIX 1; Partner of PIX-alpha; Partner of PIXA; PPM1E; CAMKN; KIAA1072; POPX1

Protein phosphatase that inactivates multifunctional CaM kinases such as CAMK4 and CAMK2. Dephosphorylates and inactivates PAK. May play a role in the inhibition of actin fiber stress breakdown and in morphological changes driven by TNK2/CDC42. Dephosphorylates PRKAA2.
