    Summary
    This gene encodes a protein that contains three tetratricopeptide repeats. The gene has been shown to be hormonally regulated in breast cancer cells and may play a role in cancer cell invasion and metastasis. [provided by RefSeq, Mar 2009]

    What's a GeneRIF?
    1. [A pan-cancer analysis of TTC9A expression level and its correlation with prognosis and immune microenvironment].
      Title: [A pan-cancer analysis of TTC9A expression level and its correlation with prognosis and immune microenvironment].
    2. In this study, we propose a molecular mechanism whereby TTC9 mutations function to generate ichthyosiform hyperkeratosis of the skin, either directly or indirectly through altered myofibroblasts and altered hormone regulation.
      Title: Exome sequencing in a Chinese family reveals TTC9 mutation associated with keratitis-ichthyosis-deafness (KID) syndrome.
    3. It is plausible therefore that TTC9A negatively regulates ERalpha activity through interacting with co-chaperone proteins such as FKBP38 and FKBP51.
      Title: Tetratricopeptide repeat domain 9A negatively regulates estrogen receptor alpha activity.
    4. TTC9A acts as a chaperone protein to facilitate the function of tropomyosins (including Tm5NM-1) in stabilizing microfilament and it may play a role in cancer cell invasion and metastasis
      Title: Tetratricopeptide repeat domain 9A is an interacting protein for tropomyosin Tm5NM-1.

    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.
