vps-28 encodes the C. elegans ortholog of S. cerevisiae vacuolar protein sorting protein Vps28p and human VPS28; VPS-28 is a component of the C. elegans ESCRT-1 (Endosomal Sorting Complex Required for Transport, other members include VPS-37, MVB-12, and TSG-101) that is required for cell surface receptor degradation via the multivesicular body sorting pathway and hence, downregulation of receptor activity.
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
