TMEM184B (transmembrane protein 184B), also known as FM08, HS5O6A or C22orf5, is a 407 amino acid multi-pass membrane protein that is thought to play a role in the activation of the MAPK (mitogen-activated protein kinase) signaling pathway. The gene encoding TMEM184B maps to human chromosome 22, which houses over 500 genes and is the second smallest human chromosome. Mutations in several of the genes that map to chromosome 22 are involved in the development of Phelan-McDermid syndrome, Neurofibromatosis type 2, autism and schizophrenia. Additionally, translocations between chromosomes 9 and 22 may lead to the formation of the Philadelphia Chromosome and the subsequent production of the novel fusion protein BCR-Abl, a potent cell proliferation activator found in several types of leukemias. |
