Based on studies in mice, the transcription factor ISL1, in complex with either LHX3 or LHX4, directly stimulates transcription of the SLIT2 gene. ISL1-mediated regulation of SLIT2 gene transcription in branchiomotor (BM) neurons and somatic motor (SM) neurons involves LHX4 and LHX3, respectively (Kim et al. 2016). Slit2 expression is diminished in Isl1 mutant mice (Lee et al. 2015).
SLIT2 is one of gene suggested to be repressed by the transcription factor ARX, involved in neuronal proliferation, migration, maturation and differentiation, as well as axon guidance (reviewed by Friocourt and Parnavelas, 2011).
