26S proteasome complex subunit SEM1 is a protein that in humans is encoded by the SEM1 gene (previously SHFM1). In yeast biology and general proteasome nomenclature, it is referred to as Rpn15 (Regulatory Particle Non-ATPase subunit 15).

Function

The product of this gene has been localized within the split hand/split foot malformation locus SHFM1 at chromosome 7. It has been proposed to be a candidate gene for the autosomal dominant form of the heterogeneous limb developmental disorder split hand/split foot malformation type 1. In addition, it has been shown to directly interact with BRCA2. It also may play a role in the completion of the cell cycle.

Interactions

SHFM1 has been shown to interact with BRCA2.
