Anti-MLC1 Antibody, clone XB6-AC5

Membrane protein MLC1 (UniProt: Q8VHK5; also known as MLC1) is encoded by the Mlc1 gene (Gene ID: 170790) in murine species. MLC1 is a multi-pass membrane protein that regulates the response of astrocytes to hypo-osmosis by promoting calcium influx. It is a highly hydrophobic protein with eight transmembrane domains and short amino and carboxylic- cytoplasmic tails. It forms highly stable dimeric and oligomeric structures. Within the brain, it is mainly expressed in astrocytes, particularly at the astrocyte end-feet contacting the blood-brain barrier and the pial membrane. MLC1 may also be involved in transporting molecules across the blood-brain barrier and the brain-cerebrospinal fluid barrier. Its higher expression in astrocytes contacting blood vessels suggest its role in the regulation of ion and water homeostasis. Studies have shown that MLC1 establishes structural and/or functional interactions with several ion/water channels and transporters and ion channel accessory proteins. These interactions are affected by mutations in Mlc1 gene that cause Megalencephalic leukoencephalopathy with subcortical cysts (MLC) that is characterized mainly by myelin vacuolization and early onset of macrocephaly, early in life. GlialCAM is reported to be essential for MLC1 endoplasmic reticulum exit and targeting to astrocyte-astrocyte junctions. Mutations in Glial CAM are also observed in about 50% of subjects with MLC. MLC1 is phosphorylated at its N- and C-terminal regions by both PKA and PKC and PKC alone, respectively. Treatment with agents that activate PKC or PKA or with phosphatase inhibitors is reported to modify MLC1 plasma membrane expression and formation of multimeric structures.
