Protein Information (annotations from UniProt)

Database IDHIV0006914
UniProt IDP08865
Primary gene name(s)RPSA
Synonym gene name(s)LAMBR, LAMR1
Protein name40S ribosomal protein SA
Protein functionRequired for the assembly and/or stability of the 40S ribosomal subunit. Required for the processing of the 20S rRNA-precursor to mature 18S rRNA in a late step of the maturation of 40S ribosomal subunits. Also functions as a cell surface receptor for laminin. Plays a role in cell adhesion to the basement membrane and in the consequent activation of signaling transduction pathways. May play a role in cell fate determination and tissue morphogenesis. Acts as a PPP1R16B-dependent substrate of PPP1CA. {ECO:0000255|HAMAP-Rule:MF_03016, ECO:0000269|PubMed:16263087, ECO:0000269|PubMed:6300843}.; FUNCTION:, Microbial infection Acts as a receptor for the adeno-associated viruses 2,3,8 and 9, dengue virus, Sindbis virus and Venezuelan equine encephalitis virus, PubMed:1385835, PubMed:15507651, PubMed:16973587. Also acts as a receptor for pathogenic prion protein and bacteria, PubMed:9396609, PubMed:11689427, PubMed:15516338. {ECO:0000269|PubMed:11689427, ECO:0000269|PubMed:1385835, ECO:0000269|PubMed:15507651, ECO:0000269|PubMed:15516338, ECO:0000269|PubMed:16973587, ECO:0000269|PubMed:9396609}.
Subcellular locationCell membrane. Cytoplasm. Nucleus {ECO:0000255|HAMAP-Rule:MF_03016}. Note=67LR is found at the surface of the plasma membrane, with its C-terminal laminin-binding domain accessible to extracellular ligands. 37LRP is found at the cell surface, in the cytoplasm and in the nucleus, By similarity. Colocalizes with PPP1R16B in the cell membrane. {ECO:0000255|HAMAP-Rule:MF_03016}.
