Notes: 45 kDa Calcium-binding protein (Cab45), also known as stromal cell-derived factor 4 (SDF-4), is a member of the Cab45/reticulocalbin/ERC45/calumenin (CREC) protein family encoded by SDF4 in humans.{72515,72514} SDF4 encodes a 362-amino acid precursor protein that contains an N-terminal signal sequence, six EF-hand motifs, and a C-terminal HEEF motif. Alternative splicing produces three isoforms: the Golgi-localized variant Cab45-G, the cytosolic variant Cab45-C, and the secreted variant Cab45-S, each with different domain composition, as well as physiological and pathophysiological roles.{72515,72514,72516} Cab45 levels are increased in PANC-1 pancreatic, LIM1215 colorectal, and HeLa cervical cancer cells.{72516} SDF4-/- induces perinuclear accumulation of lysosomes and secretion of the unprocessed protein precursors prosaposin and progranulin in HeLa cells, indicating a role for Cab45 in lysosomal positioning.{72517}
