Specificity

Detects human, mouse, and rat PI 3‑Kinase p55 gamma in Western blots. In direct ELISAs, less than 10% cross-reactivity with recombinant human (rh) PIK3R1 (aa 519‑644) and no cross-reactivity with rhPIK3R1 (aa 328-431), rhPIK3R2 (aa 325-428), rhPIK3R2 (aa 516-642), rhPIK3C3 (aa 419‑887), rhPIK3R4 (aa 58-230), or rhPIK3R5 (aa 530-726) is observed.

Scientific Data Images for PI 3-Kinase p55 gamma Antibody (668619)

Detection of Human, Mouse, and Rat PI 3‑Kinase p55 gamma by Western Blot.

Western blot shows lysates of HEK293 human embryonic kidney cell line, NIH-3T3 mouse embryonic fibroblast cell line, and L6 rat myoblast cell line. PVDF Membrane was probed with 1 µg/mL of Human/Mouse/Rat PI 3-Kinase p55 gamma Monoclonal Antibody (Catalog # MAB6638) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for p55 gamma at approximately 55 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: PI 3-Kinase p55 gamma

p55 gamma (Protein of 55 kDa, gamma subunit; also PI3-kinase regulatory subunit gamma and p55PIK) is a 55-57 kDa member of the PI3K p85 family of regulatory subunits. It is widely expressed, and serves as a recruitment subunit for the p110 catalytic subunit of PI3 kinase. p55 gamma /p55PIK should not be confused with the 55 kDa alpha splice variant of the p85a gene (75% amino acid [aa] identity). Human p55 gamma is 461 aa in length. It contains a unique 34 aa N-terminus that binds Rb and prevents cycle progression, followed by a Pro-rich region (aa 35-44) and two SH2 domains that bind the p110 catalytic subunit (aa 65-160 and 358-452). Based on mouse, it is likely that alternate start sites at Met8 and Met32 generate 54 and 50 kDa protein products, respectively. There is also a potential for a start site 18 aa upstream of the standard start site, as well as a splice form that shows a deletion of aa 256-314 that may be accompanied by an additional deletion of aa 36-71. Over aa 251-378, human p55 gamma shares 94% aa identity with mouse p55 gamma.
