Human Gene MFRP (ENST00000619721.6) from GENCODE V44
  Description: Homo sapiens membrane frizzled-related protein (MFRP), mRNA. (from RefSeq NM_031433)
RefSeq Summary (NM_015645): This gene encodes a member of a family of proteins that function as components of basement membranes and may play a role in cell adhesion. Mutations in this gene have been associated with late-onset retinal degeneration. The protein may be encoded by either a bicistronic transcript including sequence from the upstream membrane frizzled-related protein gene (MFRP), or by a monocistronic transcript expressed from an internal promoter. [provided by RefSeq, Jun 2013].

-  Comments and Description Text from UniProtKB
DESCRIPTION: RecName: Full=Membrane frizzled-related protein; AltName: Full=Membrane-type frizzled-related protein;
FUNCTION: May play a role in eye development.
SUBCELLULAR LOCATION: Membrane; Single-pass type II membrane protein (Potential).
TISSUE SPECIFICITY: Specifically expressed in brain. Strongly expressed in medulla oblongata and to a lower extent in hippocampus and corpus callosum. Expressed in keratinocytes.
DEVELOPMENTAL STAGE: Expressed in fetal brain.
DISEASE: Defects in MFRP are the cause of nanophthalmos 2 (NNO2) [MIM:609549]. NNO2 is a rare autosomal recessive disorder of eye development characterized by extreme hyperopia and small functional eyes.
DISEASE: Defects in MFRP are the cause of microphthalmia isolated type 5 (MCOP5) [MIM:611040]. Microphthalmia is a clinically heterogeneous disorder of eye formation, ranging from small size of a single eye to complete bilateral absence of ocular tissues. Ocular abnormalities like opacities of the cornea and lens, scaring of the retina and choroid, cataract and other abnormalities like cataract may also be present. MCOP5 is characterized by posterior microphthalmia, retinitis pigmentosa, foveoschisis and optic disc drusen.
SIMILARITY: Contains 2 CUB domains.
SIMILARITY: Contains 1 FZ (frizzled) domain.
SIMILARITY: Contains 2 LDL-receptor class A domains.

ModBase Predicted Comparative 3D Structure on Q9BY79
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.
