Immunopharmacology Comments
LYN is a Src family tyrosine kinase, expressed predominantly in hematopoietic cells, but also in neural, liver, and adipose tissues. LYN appears to function as a rheostat to modulate B cell signaling, and can be activating or inhibitory in action, depending on the B cell receptor and interacting protein complement present in particular cells [10-11,21].
