This review will describe the SH2-domain signaling protein Src Homology-2 domaincontaining protein B (SHB) and its role in various physiological processes relating inparticular to glucose homeostasis andbcell function. SHB operates downstream of severaltyrosine kinase receptors and assembles signaling complexes in response to receptoractivation by interacting with other signaling proteins via its other domains (proline-rich,phosphotyrosine-binding and tyrosine-phosphorylation sites). The subsequent responsesare context-dependent. Absence ofShbin mice has been found to exert effects onhematopoiesis, angiogenesis and glucose metabolism. Specifically, first-phase insulinsecretion in response to glucose was impaired and this effect was related to alteredcharacteristics of focal adhesion kinase activation modulating signaling through Akt, ERK,bcatenin and cAMP. It is believed that SHB plays a role in integrating adaptive responses tovarious stimuli by simultaneously modulating cellular responses in different cell-types, thusplaying a role in maintaining physiological homeostasis
