Protein-coding gene in the species Homo sapiens
Src kinase-associated phosphoprotein 2 is an enzyme that in humans is encoded by the SKAP2 gene .[ 5] [ 6] [ 7]
The protein encoded by this gene belongs to the src family kinases . This protein is similar to the src kinase associated phosphoprotein 1 . It is an adaptor protein that is thought to play an essential role in the src signaling pathway in various cells, but particularly specific in macrophages . It inhibits PTK2B/RAFTK activity and regulates alpha-synuclein phosphorylation.[ 7] Signal-regulatory protein alpha and directs integrin -activated cytoskeletal reorganization in macrophages.[ 8]
