Meis homeobox 3: Proteins and Enzymes

MEIS3, also known as Homeobox protein Meis3, has 3 isoforms, a 375 amino acid isoform that is 41 kDa, a 421 amino acid isoform that is 46 kDa, and a 358 amino acid isoform that is 39 kDa, and is nucleus located. Little is currently known about its function. Studies are performed on the relationship of this protein to neuronitis. MEIS3 protein involvement has been observed with relation to HOXA13 in the regulation of transcription, DNA-dependent, negative regulation of apoptotic process, and positive regulation of protein kinase B signaling cascade pathways.
