Summary
This gene encodes a cysteine-rich hydrophobic (CHIC) domain-containing protein, and is one of the few protein-coding genes found near the X-inactivation center. Studies in mouse indicate that the mouse ortholog of this gene is subject to X-inactivation in mouse. Experiments with other CHIC domain-containing family members show that the cysteine residues are palmitoylated post-translationally, resulting in membrane association. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, May 2017]

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.
