Enables several functions, including gamma-tubulin binding activity; signaling receptor binding activity; and ubiquitin protein ligase binding activity. Involved in several processes, including histamine secretion by mast cell; neurogenesis; and positive regulation of Fc receptor mediated stimulatory signaling pathway. Located in several cellular components, including adherens junction; mitochondrial envelope; and postsynaptic density. Part of integrin alpha2-beta1 complex. Is active in glutamatergic synapse and postsynaptic specialization, intracellular component. Biomarker of Parkinsonism and endometriosis. Orthologous to human LYN (LYN proto-oncogene, Src family tyrosine kinase). [provided by Alliance of Genome Resources, Apr 2022]
