Location

Nucleus/Cytoplasm

Interaction

Transcription factor SOX-10. Transcription factor that seems to function synergistically with the POU domain protein TST-1/OCT6/SCIP. This gene encodes a member of the SOX (SRY-related HMG-box) family of transcription factors involved in the regulation of embryonic development and in the determination of the cell fate. The encoded protein may act as a transcriptional activator after forming a protein complex with other proteins.

Pathway

SRY related HMG box gene 10,expressed in neural crest cells during early development and in glial cells of the peripheral and central nervous system during late development and in adult, playing an essential role in the development of neural-crest-derived human cell lineages, homolog to mouse dominant megacolon (Dom).






MUTATION

Allele or SNP

9 phenotypic alleles of Dom are described in MGI:98358.

SNPs deposited in dbSNP Build 128.

Distribution

The 9 phenotypic alleles include 5 targeted and other, 1 spontaneous, 1 chemically induced, and 2 radiation induced.

(Numbering of cDNA sequence is based on the start codon of RefSeq NM_011437. view ORF here.)

Effect

Mutations in this gene result in dominant megacolon.






PHENOTYPE

Defects in Sox10 are the cause of the mouse mutant dominant megacolon (dom). Homozygotes for null mutations lack peripheral glial cells, melanocytes, and autonomic and enteric neurons, and die neonatally or sooner. Heterozygotes exhibit white spotting and megacolon.

During N-ethyl-N-nitrosourea (ENU) mutagenesis screen utilizing a mouse model sensitized for NC defects, Sox10(LacZ/+), Erbb3(msp1) that carries a single amino acid substitution in the extracellular region of the protein shows altered neural crest patterning (Buac et al.). This group also identified that a null mutation of Gli3 causes the increased hypopigmentation in Sox10(LacZ/+) (Matera et al.).
