    Summary
    Enables transmembrane receptor protein tyrosine kinase adaptor activity. Involved in several processes, including positive regulation of intracellular signal transduction; transmembrane receptor protein tyrosine kinase signaling pathway; and triglyceride homeostasis. Located in cell cortex. Is expressed in adult fat body; adult gut; adult head; hypodermal muscle cell of A1-7; and indirect flight muscle cell. Human ortholog(s) of this gene implicated in essential thrombocythemia; familial erythrocytosis 1; and myelofibrosis. Orthologous to several human genes including SH2B2 (SH2B adaptor protein 2).
