Dock2
Dock2 (Dedicator of cytokinesis 2), also known as DOCK2, is a large (~180 kDa) protein involved in intracellular signalling networks.〔(【引用サイトリンク】 url = http://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=1794 )〕 It is a member of the DOCK-A subfamily of the DOCK family of guanine nucleotide exchange factors (GEFs) which function as activators of small G proteins. Dock2 specifically activates isoforms of the small G protein Rac. ==Discovery== Dock2 was first characterised as one of a number of proteins which shared high sequence similarity with the previously described protein Dock180, the archetypal member of the DOCK family. Whereas Dock180 expression is near ubiquitous in mammals, Dock2 appears to be expressed specifically in leukocytes and is considered to be the principal DOCK family member in these cells.
