Hck Rabbit Polyclonal Antibody

The protein encoded by this gene is a member of the Src family of tyrosine kinases. This protein is primarily hemopoietic, particularly in cells of the myeloid and B-lymphoid lineages. It may help couple the Fc receptor to the activation of the respiratory burst. In addition, it may play a role in neutrophil migration and in the degranulation of neutrophils. Multiple isoforms with different subcellular distributions are produced due to both alternative splicing and the use of alternative translation initiation codons, including a non-AUG (CUG) codon. [provided by RefSeq, Feb 2010], catalytic activity:ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate., domain:The SH3 domain mediates binding to HIV-1 Nef., function:May serve as part of a signaling pathway coupling the Fc receptor to the activation of the respiratory burst. May also contribute to neutrophil migration and may regulate the degranulation process of neutrophils., PTM:Isoform p59-HCK contains a N-myristoyl glycine at position 3 (By similarity) . Isoform p59-HCK contains a S-palmitoyl cysteine at position 3., similarity:Belongs to the protein kinase superfamily. Tyr protein kinase family. SRC subfamily., similarity:Contains 1 protein kinase domain., similarity:Contains 1 SH2 domain., similarity:Contains 1 SH3 domain., subunit:May interact (via SH3 domain) with HIV-1 Nef and Vif. This interaction would stimulates its tyrosine-kinase activity. Interacts (via SH3 domain) with HEV ORF3 protein., tissue specificity:Expressed predominantly in cells of the myeloid and B-lymphoid lineages.
