Human Gene CABP4 (ENST00000438189.6) from GENCODE V44
Description: Homo sapiens calcium binding protein 4 (CABP4), transcript variant 4, mRNA. (from RefSeq NM_001379183) RefSeq Summary (NM_001300896): This gene encodes a member of the CABP family of calcium binding protein characterized by four EF-hand motifs. Mutations in this gene are associated with congenital stationary night blindness type 2B. Three transcript variants encoding two different isoforms have been found for this gene.

Gencode Transcript: ENST00000438189.6 Gencode Gene: ENSG00000175544.14 Transcript (Including UTRs) Position: hg38 chr11:67,452,415-67,459,228 Size: 6,814 Total Exon Count: 7 Strand: + Coding Region Position: hg38 chr11:67,456,137-67,458,659 Size: 2,523 Coding Exon Count: 5
ID:CABP4_HUMAN DESCRIPTION: RecName: Full=Calcium-binding protein 4; Short=CaBP4; FUNCTION: Involved in normal synaptic function through regulation of Ca(2+) influx and neurotransmitter release in photoreceptor synaptic terminals and in auditory transmission. Modulator of CACNA1D and CACNA1F, suppressing the calcium-dependent inactivation and shifting the activation range to more hyperpolarized voltages (By similarity). SUBUNIT: Interacts with CACNA1F and CACNA1D (via IQ domain) in a calcium independent manner (By similarity). Interacts (via N- terminus) with UNC119 (By similarity). SUBCELLULAR LOCATION: Cytoplasm. Note=Found in rod spherules and cone pedicles of the presynapses from both types of photoreceptors (By similarity). TISSUE SPECIFICITY: Expressed in retina and in the inner hair cells (IHC) of the cochlea. PTM: Phosphorylated. Phosphorylation levels change with the light conditions and regulate the activity (By similarity). DISEASE: Defects in CABP4 are the cause of congenital stationary night blindness type 2B (CSNB2B) [MIM:610427]. Congenital stationary night blindness is a non-progressive retinal disorder characterized by impaired night vision. SIMILARITY: Contains 4 EF-hand domains.

The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

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.
