MPHOSPH9-: Proteins and Enzymes

MPHOSPH9, also known as M-phase phosphoprotein 9, has 2 isoforms, a 1,031 amino acid isoform 1 that is 116 kDa and a 1,028 amino acid isoform 2 that is 116 kDa, localizes to the distal and proximal end of centriole pairs in duplicated centrosomes, and in ciliated cells, localizes to the distal and proximal end of daughter centriole and proximal of the mother centriole but not in the distal end of the mother centriole. Little is known about its function. Studies on this protein have shown a relationship with the following diseases and disorders: corneal ulcer, rosacea, multiple sclerosis, Fanconi's anemia, anemia, and neuronitis. This protein has also shown an interaction with YWHAG, USP11, SVIL, YWHAZ, WNK1, and UBC in M phase of mitotic cell cycle pathways.
