Cherukuri et al., J Immunol 2004
:
Using B cells from CD81-deficient mice we demonstrate that in the absence of CD81, coligated BCR and
CD19/CD21 complexes fail to partition into lipid rafts and
enhance BCR signaling from rafts
Ishiura et al., Eur J Immunol 2010
(Lymphoma, B-Cell) :
BCR engagement
induced differential tyrosine phosphorylation, as CD19-Y ( 513 ) phophorylation occurred first, and
CD19-Y ( 482 ) phosphorylation was delayed and transient ... Different BCR isotypes exhibited distinct patterns of CD19 phosphorylation :
IgG-BCR ligation
resulted in faster phosphorylation of
CD19-Y ( 513 ) and more intense phosphorylation of CD19-Y ( 391 ) than IgM-BCR ligation
Sato et al., Proc Natl Acad Sci U S A 1997
:
Ligation of
CD19 and CD22 in vivo is likely to positively and negatively
regulate BCR signaling, respectively, because CD19 crosslinking was more efficient than BCR crosslinking at inducing Vav phosphorylation
