Publication Link Summary of findings
17893707 Observational study of gene-disease association. (HuGE Navigator)
17961073 Observational study of gene-disease association. (HuGE Navigator)
17712477 Expression of saposin C-originated saposin C may upregulate AR gene expression and activate the androgen receptor transcriptional function in an androgen-independent manner in prostate cancer cells.
16080200 Amplification and overexpression of PSAP was studied in prostatic neoplasms.
16823039 determination of crystal structure of human saposins A and C to 2.0 Angstroms and 2.4 Angstroms, respectively and both reveal the compact, monomeric saposin fold
17561962 an unglycosylated Sap-B variant, Asn215His, which causes a fatal sphingolipid storage disease, lost the ability to extract membrane lipids at acidic pH in the presence of BMP
17300216 FSAP (Factor VII-activating protease) can cleave and inactivate PDGF-BB (platelet-derived growth factor-BB) and thereby inhibits VSMC (vascular smooth-muscle cell) proliferation.
17372201 saposin B may facilitate lipid binding to CD1d molecules throughout the endocytic pathway
14674747 The structure of saposin C compared to other saposin-fold family members provides an explanation for function variability of this protein family.
15305334 There might be a potential pleuripotent regulatory function for prosaposin in prostate cancer.
