Receptor tyrosine kinase ligation induces autophosphorylation of tyrosine residues within the cytoplasmic region and activation of proteins containing Src homology 2 (SH2) domains, such as PLCγ, PI-3 kinase, Shc, and SH2-B. Three alternatively spliced isoforms of SH2-B (α, β, γ) function as tyrosine kinase receptor adaptor proteins. Although each contains an N-terminal pleckstrin homology (PH) domain and a C-terminal SH2 domain, they differ in their C-termini downstream of the SH2 domain. SH2-B isoforms are expressed in a variety of tissues, including brain, lung, muscle, kidney, heart, and ovary. In neurons, SH2-Bβ binds to TrkA, TrkB, and TrkC receptors and is a substrate for TrkA receptor-mediated phosphorylation. In PC12 cells, SH2-Bβ is phosphorylated at multiple Ser/Thr residues by kinases in the MEK/ERK cascade and is required for NGF-induced differentiation. Additionally, SH2-Bβ binds to activated insulin and PDGF receptors and binds to and acts as a substrate for JAK2 tyrosine kinase during growth hormone signaling. Thus, SH2-B proteins are important signaling molecules in tyrosine kinase receptor pathways, especially those mediating neuronal differentiation.
