Automated description from the Alliance of Genome Resources (Release 7.1.0)
Enables identical protein binding activity and transmembrane signaling receptor activity. Involved in B cell receptor signaling pathway. Acts upstream of or within response to bacterium. Located in external side of plasma membrane. Part of B cell receptor complex. Is expressed in several structures, including alimentary system; brain; genitourinary system; hemolymphoid system gland; and liver and biliary system. Human ortholog(s) of this gene implicated in agammaglobulinemia 6 and lymphoma (multiple). Orthologous to human CD79B (CD79b molecule).
