Immunoglobulin-binding protein 1 is a protein that in humans is encoded by the IGBP1 gene.^[5]^[6]

Function[edit]

The proliferation and differentiation of B cells is dependent upon a B-cell antigen receptor (BCR) complex. Binding of antigens to specific B-cell receptors results in a tyrosine phosphorylation reaction through the BCR complex and leads to multiple signal transduction pathways.^[6]

Interactions[edit]

IGBP1 has been shown to interact with PPP4C,^[7]^[8]^[9] PPP6C^[8]^[9] and PPP2CA.^[8]^[9]^[10]^[11]
