mouse monoclonal IgG2b; GRASP55 Antibody (E-5) is an IgG2b κ mouse monoclonal GRASP55 antibody (also designated GRASP55 antibody) that detects the GRASP55 protein of mouse, rat and human origin by WB, IP, IF and ELISA. GRASP55 Antibody (E-5) is available as both the non-conjugated anti-GRASP55 antibody form, as well as multiple conjugated forms of anti-GRASP55 antibody, including agarose, HRP, PE, FITC and multiple Alexa Fluor® conjugates. The Golgi apparatus is a highly complex organelle comprised of a stack of cisternal membranes on the secretory pathway from the ER to the cell surface. The structure is maintained by an exoskeleton or Golgi matrix constructed from a family of coiled-coil protein, the golgins and other peripheral membrane components such as GRASP55 and GRASP65. GRASP55 (Golgi reassembly stacking protien or p59) is a component of the Golgi stacking machinery. GRASP55 is highly homologous to GRASP65 and contains two PDZ domains. GRASP55 is myristoylated and palmitoylated. Unlike GRASP65, GRASP55 does not have detectable binding with the vesicle docking protein GM130 and is located on the medial-Golgi rather than cis-Golgi. Both GRASP55 and GRASP65 function in the stacking of Golgi Cisternae. The novel coiled-coil protein golgin 45 interacts with GRASP55 and the GTP form of Rab 2, suggesting that GRASP55 and golgin 45 form a Rab 2 effector complex on medial-Golgi essential for normal protein transport and Golgi structure. ERK2 directly phosphorylates GRASP55, which is phosphorylated in mitotic cells, suggesting that mitogen-activated protein kinase kinase (MKK)/ERK pathway phosphorylates the Golgi during mitosis.
