Summary: Enables DNA-binding transcription activator activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and chromatin binding activity. Involved in negative regulation of neurogenesis; positive regulation of neural precursor cell proliferation; and regulation of gene expression. Acts upstream of or within several processes, including hair follicle development; maintenance of epithelial cell apical/basal polarity; and nervous system development. Located in nucleus. Is expressed in several structures, including branchial arch; limb; nervous system; sensory organ; and septum transversum. Orthologous to human LHX2 (LIM homeobox 2).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

See identical proteins and their annotated locations for NP_001277575.1

Status: VALIDATED

Description

Transcript Variant: This variant (2) contains an alternate 5' terminal exon and it thus differs in the 5' UTR and initiates translation at a downstream in-frame start codon, compared to variant 1. The encoded isoform (b) is shorter at the N-terminus, compared to isoform a.
