LMX1A
Template:Short description Template:Infobox gene LIM homeobox transcription factor 1, alpha, also known as LMX1A, is a protein which in humans is encoded by the LMX1A gene.[1][2]
Function
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.[3]
Interactions
LMX1A has been shown to interact with TCF3[4] and LHX3.[5]
