Quick Overview for PAG1 antibody (N-Term) (ABIN2745550)

Target: PAG1 (phosphoprotein Associated with Glycosphingolipid Microdomains 1 (PAG1))

Reactivity: Human, Mouse, Rat

Host: Rabbit

Clonality: Polyclonal

Conjugate: This PAG1 antibody is un-conjugated

Application: Western Blotting (WB), Immunoprecipitation (IP), Immunocytochemistry (ICC)

Product Details anti-PAG1 Antibody

Binding Specificity: AA 412-424, N-Term

Purpose: anti-PAG [Cbp], pAb (IG-452)

Specificity: Recognizes mouse, rat and human PAG/Cbp.

Characteristics: Polyclonal Antibody. Recognizes mouse, rat and human PAG/Cbp. Source: Rabbit. Applications: ICC, IP, WB. Liquid. In PBS containing 0.02 % sodium azide. PAG is a ubiquitously expressed transmembrane adapter protein. Depending on its phosphorylation status, it appears as diffuse band(s) of 80-90 kDa by SDS-PAGE, with phosphorylation leading to a shift towards a higher apparent molecular mass. Tyrosine phosphorylated PAG recruits Csk to the membrane and negatively regulates Src family kinases via Csk-mediated phosphorylation. Upon T cell receptor engagement, PAG becomes dephosphorylated, thereby displacing Csk from the membrane and enabling the activation of the Src kinases Fyn and Lck. PAG negatively regulates TCR (T cell antigen receptor)-mediated signaling in T cells and FCER1 (high affinity immunoglobulin epsilon receptor)-mediated signaling in mast cells. It promotes CSK activation and recruitment to lipid rafts, which results in LCK inhibition. It inhibits immunological synapse formation by preventing dynamic arrangement of lipid raft proteins and may be involved in cell adhesion signaling.

Purification: Antigen affinity purified.

Purity: Antigen affinity purified.

Immunogen: Synthetic peptide corresponding to aa 412-424 of the N-terminal rat PAG including an additional N-terminal Cys residue.
