Human Gene CRYM (ENST00000219599.8) from GENCODE V44
  Description: Homo sapiens crystallin mu (CRYM), transcript variant 1, mRNA. (from RefSeq NM_001888)
RefSeq Summary (NM_001888): Crystallins are separated into two classes: taxon-specific and ubiquitous. The former class is also called phylogenetically-restricted crystallins. The latter class constitutes the major proteins of vertebrate eye lens and maintains the transparency and refractive index of the lens. This gene encodes a taxon-specific crystallin protein that binds NADPH and has sequence similarity to bacterial ornithine cyclodeaminases. The encoded protein does not perform a structural role in lens tissue, and instead it binds thyroid hormone for possible regulatory or developmental roles. Mutations in this gene have been associated with autosomal dominant non-syndromic deafness. [provided by RefSeq, Sep 2014].

-  Comments and Description Text from UniProtKB
  ID: CRYM_HUMAN
DESCRIPTION: RecName: Full=Thiomorpholine-carboxylate dehydrogenase; EC=1.5.1.25; AltName: Full=Mu-crystallin homolog; AltName: Full=NADP-regulated thyroid-hormone-binding protein; AltName: Full=ketimine reductase;
FUNCTION: Specifically catalyzes the reduction of imine bonds in brain substrates that may include cystathionine ketimine (CysK) and lanthionine ketimine (LK). Binds thyroid hormone which is a strong reversible inhibitor. Presumably involved in the regulation of the free intracellular concentration of triiodothyronine and access to its nuclear receptors.
CATALYTIC ACTIVITY: Thiomorpholine 3-carboxylate + NAD(P)(+) = 3,4-dehydro-thiomorpholine-3-carboxylate + NAD(P)H.
COFACTOR: NAD or NADP.
BIOPHYSICOCHEMICAL PROPERTIES: pH dependence: Optimum pH is 4.5;
SUBUNIT: Homodimer.
SUBCELLULAR LOCATION: Cytoplasm.
TISSUE SPECIFICITY: Expressed in neural tissue, muscle and kidney.
SIMILARITY: Belongs to the ornithine cyclodeaminase family.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
