Product Specifications

Immunogen

Recombinant intracellular fragment (aa 97-432) of human Cbp (PAG).

Specificity

The polyclonal antibody recognizes Csk-binding protein (Cbp / PAG), a 46 kDa ubiquitously expressed transmembrane adaptor protein present in membrane rafts (glycosphingolipid-enriched microdomains), which however migrates on SDS PAGE gels anomalously as an 80 kDa molecule.

Clonality

Polyclonal

Host

Rabbit

Isotype

IgG

Theoretical MW

46 kDa.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Western Blot: PAG1 Antibody [NB500-541]

Analysis of human PAG using rabbit polyclonal antibody PAb (409) on lysates of Daudi and Ramos cell line under reducing and non-reducing conditions. Nitrocellulose membrane was probed with 2 µg/ml of rabbit anti-PAG monoclonal antibody followed by IRDye800-conjugated anti-rabbit secondary antibody. PAG was detected around 65 kDa.

Background: PAG1

PAG (phosphoprotein associated with GEMs), also known as Cbp (Csk-binding protein), is a ubiquitously expressed 46 kDa transmembrane adaptor protein present in membrane rafts (glycosphingolipid-enriched microdomains), which however migrates on SDS PAGE gels anomalously as an 80 kDa molecule. Following tyrosine phosphorylation by Src family kinases, PAG binds and thereby activates the protein tyrosine kinase Csk, the major negative regulator of the Src family kinases. Signaling via the B-cell receptor in B cells or high affinity IgE receptor (FcepsilonRI) in mast cells leads to PAG increased tyrosine phosphorylation and Csk binding, while T cell receptor signaling causes PAG dephosphorylation, loss of Csk binding and increased activation of the protein tyrosine kinase Lck.
