Technical Data
PAG3, phosphorylated (Tyr724) (Paxillin-associated Protein with ADP-ribosylation Factor GTPase-activating Protein 3)
PAG3 (paxillin-associated protein with ADP-ribosylation factor [ARF] GTPase-activating protein GAP] activity, number 3) is a member of the ARF GAP family of proteins that associates with the cytoskeleton, plays an important role in mediating actin cytoskeletal organization in response to adhesion and growth factor stimulation and is involved in paxillin subcellular localization. During monocyte maturation, the elevation of paxillin expression and integrin activation is associated with the induction of PAG3 expression. Overexpression of PAG3 inhibits paxillin recruitment to focal contacts and hinders cellular migration. PAG3 is phosphorylated by Pyk2 kinase on tyrosines 724 and 763.

Suitable for use in Western Blot. Other applications not tested.

Recommended Dilution:
Western Blot: 1:1000
Optimal dilutions to be determined by the researcher.

Positive Control:
COS cells overexpressing human wild-type PAG3, cotransfected with mouse Pyk2.
