SCAPER

SCAPER (S-phase CyclinA Associated Protein residing in the Endoplasmic Reticulum) is a gene located on the long arm of chromosome 15 (15q24.3). It was first identified in 2007.[1]

Gene

This gene lies on the Crick strand and has 30 exons.

Protein

The gene encodes a 1399-amino acid protein with a predicted weight of 158 kiloDaltons. It has a C2H2-type zinc finger motif, a putative transmembrane domain, an ER retrieval signal at the C terminus, 4 coiled-coil domains, 6 potential RXL motifs and 6 consensus Cdk phosphorylation sites.

Biochemistry

The encoded protein is found in the nucleus and endoplasmic reticulum.

It is found in all tissues tested. It appears to have a role in the cell cycle.

Clinical significance

Mutations in this gene have been associated with intellectual disability and retinitis pigmentosa.[2][3][4]
