mouse monoclonal IgG1; Fyn Antibody (15) is an IgG1 κ mouse monoclonal Fyn antibody (also designated Proto-oncogene Syn antibody, p59-Fyn antibody or Src-like kinase (SLK) antibody) that detects the Fyn protein of mouse, rat and human origin by WB, IP, IF, IHC(P) and FCM. Fyn Antibody (15) is available as both the non-conjugated anti-Fyn antibody form, as well as multiple conjugated forms of anti-Fyn antibody, including agarose, HRP, PE, FITC and multiple Alexa Fluor® conjugates. Src is the human homolog of the v-src gene of the Rous sarcoma virus, also called avian sarcoma virus or ASV. Src was the first proto-oncogenic non-receptor tyrosine kinase characterized in human. By virtue of common structural motifs, the Src family is composed of nine members in vertebrates, including Src, Yes, Fgr, Frk, Fyn, Lyn, Hck, Lck and Blk. Src-family kinases transduce signals that are involved in the control of a variety of cellular processes, including proliferation, differentiation, motility, and adhesion. Src-family kinases contain an amino terminal cell membrane anchor followed by an SH3 domain and an SH2 domain involved in modular association and activation, respectively. Src-family kinases are normally maintained in an inactive state and can be activated transiently during cellular events such as mitosis. Different subcellular localizations of Src-family kinases may be important for the regulation of specific cellular processes such as mitogenesis, cytoskeletal organization, and membrane trafficking. Fyn and Lck kinases play a key role in T-cell antigen receptor (TCR) signaling. The human Fyn gene maps to chromosome 6q21 and encodes a 537 amino acid protein.
