{{Infobox_gene}}Arf-GAP with SH3 domain, ANK repeat and PH domain-containing protein 2 is a protein that in humans is encoded by the ASAP2 gene.[1][2][3]This gene encodes a multidomain protein containing an N-terminal alpha-helical region with a coiled-coil motif, followed by a pleckstrin homology (PH) domain, an Arf-GAP domain, an ankyrin homology region, a proline-rich region, and a C-terminal Src homology 3 (SH3) domain. The protein localizes in the Golgi apparatus and at the plasma membrane, where it colocalizes with protein tyrosine kinase 2-beta (PYK2). The encoded protein forms a stable complex with PYK2 in vivo. This interaction appears to be mediated by binding of its SH3 domain to the C-terminal proline-rich domain of PYK2. The encoded protein is tyrosine phosphorylated by activated PYK2. In vitro it shows strong GTPase-activating protein (GAP) activity towards the small GTPases ADP-ribosylation factor (ARF) 1 and ARF5 and weak activity towards ARF6. The encoded protein is believed to function as an ARF GAP that controls ARF-mediated vesicle budding when recruited to Golgi membranes. In addition, it functions as a substrate and downstream target for PYK2 and SRC, a pathway that may be involved in the regulation of vesicular transport.[3] InteractionsDDEF2 has been shown to interact with PTK2B.[4] References1. ^{{cite journal | vauthors = Andreev J, Simon JP, Sabatini DD, Kam J, Plowman G, Randazzo PA, Schlessinger J | title = Identification of a New Pyk2 Target Protein with Arf-GAP Activity | journal = Mol Cell Biol | volume = 19 | issue = 3 | pages = 2338–50 |date=Mar 1999 | pmid = 10022920 | pmc = 84026 | doi = 10.1128/MCB.19.3.2338}} 2. ^{{cite journal | vauthors = Ishikawa K, Nagase T, Nakajima D, Seki N, Ohira M, Miyajima N, Tanaka A, Kotani H, Nomura N, Ohara O | title = Prediction of the coding sequences of unidentified human genes.
