Gene: FYN (FYN proto-oncogene, Src family tyrosine kinase) Homo sapiens
Symbol: FYN
Name: FYN proto-oncogene, Src family tyrosine kinase
Description: Exhibits several functions, including disordered domain specific binding activity; identical protein binding activity; and signaling receptor binding activity. Involved in several processes, including T cell receptor signaling pathway; cellular response to amyloid-beta; and peptidyl-tyrosine phosphorylation. Localizes to the cytosol; endosome; and plasma membrane. Colocalizes with the membrane raft. Implicated in Alzheimer's disease and schizophrenia. Biomarker of Alzheimer's disease.
Type: protein-coding
RefSeq Status: REVIEWED
