Dock11 (Paperback)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Dock11 (Dedicator of cytokinesis), also known as Zizimin2, is a large ( 240 kDa) protein involved in intracellular signalling networks. It is a member of the DOCK-D subfamily of the DOCK family of guanine nucleotide exchange factors (GEFs) which function as activators of small G proteins. Dock11 activates the small G protein Cdc42.Dock11 was identified as a protein which is highly expressed in Germinal center B lymphocytes. Subsequent RT-PCR analysis revealed expression of this protein in the spleen, thymus, bone marrow and in peripheral blood lymphocytes. Dock11 is expressed at lower levels in NIH-3T3 fibroblasts, C2C12 myoblasts and Neuro-2A neuroblastoma cells. Dock11 mRNA has also been detected in the pars intermedia.
