Single-minded homolog 2 is a protein that in humans is encoded by the SIM2 gene.[1][2]

Function[edit]

SIM1 and SIM2 genes are Drosophila single-minded (sim) gene homologs. The Drosophila sim gene encodes a transcription factor that is a master regulator of neurogenesis of midline cells in the central nervous system. SIM2 maps within the so-called Down syndrome chromosomal region. Based on the mapping position, its potential function as transcriptional repressor and similarity to Drosophila sim, it is proposed that SIM2 may contribute to some specific Down syndrome phenotypes[2]

Interactions[edit]

SIM2 has been shown to interact with Aryl hydrocarbon receptor nuclear translocator.[3][4][5][6]
