Summaries for ISX Gene

Entrez Gene Summary for ISX Gene

  • Homeobox genes encode DNA-binding proteins, many of which are thought to be involved in early embryonic development. Homeobox genes encode a DNA-binding domain of 60 to 63 amino acids referred to as the homeodomain. This gene is a member of the RAXLX homeobox gene family. [provided by RefSeq, Jul 2008]

GeneCards Summary for ISX Gene

ISX (Intestine-Specific Homeobox) is a Protein Coding gene. GO annotations related to this gene include sequence-specific DNA binding transcription factor activity and sequence-specific DNA binding. An important paralog of this gene is PHOX2B.

UniProtKB/Swiss-Prot for ISX Gene

  • Transcription factor that regulates gene expression in intestine. May participate in vitamin A metabolism most likely by regulating BCO1 expression in the intestine (By similarity).
