Recombinant Human CD22 Protein, MYC/DDK-tagged, C13 and N15-labeled

• Cat.No.: CD22-158H
• Product Overview: CD22 MS Standard C13 and N15-labeled recombinant protein (NP_001762) with a C-terminal MYC/DDK tag, was expressed in HEK293 cells.

Specification

• Description: Mediates B-cell B-cell interactions. May be involved in the localization of B-cells in lymphoid tissues. Binds sialylated glycoproteins; one of which is CD45. Preferentially binds to alpha-2,6-linked sialic acid. The sialic acid recognition site can be masked by cis interactions with sialic acids on the same cell surface. Upon ligand induced tyrosine phosphorylation in the immune response seems to be involved in regulation of B-cell antigen receptor signaling. Plays a role in positive regulation through interaction with Src family tyrosine kinases and may also act as an inhibitory receptor by recruiting cytoplasmic phosphatases via their SH2 domains that block signal transduction through dephosphorylation of signaling molecules.
