UniProt data
UniProt name: CDHR1_HUMAN (Q96JP9)
Gene name: CDHR1; Synonyms=KIAA1775, PCDH21, PRCAD
Organism: Homo sapiens (Human).
Function: Potential calcium-dependent cell-adhesion protein. May be required for the structural integrity of the outer segment (OS) of photoreceptor cells (By similarity). {ECO:0000250}.
Subcellular location: Cell membrane {ECO:0000250}; Single-pass membrane protein {ECO:0000250}. Note=Localized at the junction between the inner and outer segments of rod and cone photoreceptors cells. Confined to the base of the OS. Localized on the edges of nascent evaginating disks on the side of the OS opposite the connecting cilium. Expressed at postnatal day 2 at the apical tip of the rod photoreceptor cells, the site of the developing OS. Colocalized with rhodopsin between postnatal days 2 and 9 at the base of the growing OS region (By similarity). {ECO:0000250}.
Transmembrane domains:
- 701-721, 21 AA, Helical. {ECO:0000255}.
Sequence: 859 AA
