Summary
This gene encodes a scaffold protein involved in the TLR4 signaling pathway that may stimulate cytokine production and endothelial cell migration in response to invading pathogens. The encoded protein has also been described as a potential tumor suppressor that may negatively regulate proliferation, apoptosis, and invasion of cancer cells, and reduced expression of this gene has been observed in multiple human cancers. Mutations in this gene may be associated with abnormal skin pigmentation in human patients. [provided by RefSeq, Oct 2016]

  1. Findings indicate that miR-130b was highly expressed, while SAM and SH3 domain containing 1 protein (SASH1) was the opposite in both the oesophageal squamous cell carcinoma (ESCC) tissues and cells.
    Title: MiR-130b promotes the progression of oesophageal squamous cell carcinoma by targeting SASH1.
  2. These data further confirm that the SLY domain is critical for mediation of melanogenesis and suggest that Y551 may be a mutation hotspot for dyschromatosis universalis hereditaria. The p.M595T is the first heterozygous missense mutation reported in the SH3 domain.

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.
