Human Gene SMOC1 (ENST00000361956.7) Description and Page Index
  Description: Homo sapiens SPARC related modular calcium binding 1 (SMOC1), transcript variant 1, mRNA. (from RefSeq NM_001034852)
RefSeq Summary (NM_001034852): This gene encodes a multi-domain secreted protein that may have a critical role in ocular and limb development. Mutations in this gene are associated with microphthalmia and limb anomalies. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2011].

-  Comments and Description Text from UniProtKB
DESCRIPTION: RecName: Full=SPARC-related modular calcium-binding protein 1; AltName: Full=Secreted modular calcium-binding protein 1; Short=SMOC-1; Flags: Precursor;
FUNCTION: Plays essential roles in both eye and limb development. Probale regulator of osteoblast differentiation.
SUBCELLULAR LOCATION: Secreted, extracellular space, extracellular matrix, basement membrane. Note=In or around the basement membrane.
TISSUE SPECIFICITY: Widely expressed in many tissues with a strongest signal in ovary. No expression in spleen.
PTM: Glycosylated.
DISEASE: Defects in SMOC1 are the cause of ophthalmoacromelic syndrome (OAS) [MIM:206920]. A rare disorder presenting with anophthalmia or microphthalmia and limb anomalies. Limb malformations include fused 4th and 5th metacarpals and short 5th finger in hands, and olygodactyly in foot (four toes). Most patients have bilateral anophthalmia/ microphthalmia, but unilateral abnormality is also noted. Other malformations are rare, but venous or vertebral anomaly was recognized each in single cases.
SIMILARITY: Contains 2 EF-hand domains.
SIMILARITY: Contains 1 Kazal-like domain.
SIMILARITY: Contains 2 thyroglobulin type-1 domains.

ModBase Predicted Comparative 3D Structure on Q9H4F8
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.
