LIM homeobox transcription factor 1, alpha, also known as LMX1A, is a protein which in humans is encoded by the LMX1A gene. Insulin is produced exclusively by the beta cells in the islets of Langerhans in the pancreas. The level and beta-cell specificity of insulin gene expression are regulated by a set of nuclear genes that bind to specific sequences within the promoter of the insulin gene INS and interact with RNA polymerase to activate or repress transcription. LMX1 is a LIM homeobox transcription factor that binds an A/T-rich sequence in the insulin promoter and stimulates transcription of insulin. LMX1A has been shown to interact with TCF3 and LHX3. lmx1a.txt Last modified: 2024/06/07 02:52by 127.0.0.1
