What is the function of this protein?
Mediates binding to human platelets, possibly through a receptor-ligand interaction.  Probably associated with virulence in endovascular infection (PubMed:15784571).  Plays a positive role in biofilm formation, possibly by self-association via the non-repeat region (NRR or binding region, BR) (PubMed:20714350).  Binds to and plays a role in human lung epithelial cell invasion via the L-lectin module of its NRR domain; N-acetylneuraminic acid (Neu5Ac) inhibits binding.  Treatment of host cells with neuraminidase decreases adherence of S. aureus cells, suggesting SraP recognizes a host terminal Neu5Ac moiety as a receptor (PubMed:24901708).
What are the official names of this protein?
Serine-rich adhesin for platelets, Adhesin SraP, Staphylococcus aureus surface protein A, SasA.
What is the protein family that this protein belongs to?
Belongs to the serine-rich repeat protein (SRRP) family.
What are the subcellular locations of this protein?
Secreted, cell wall; Peptidoglycan-anchor. Note=Primarily exported by the accessory SecA2/SecY2 protein translocation apparatus (PubMed:18621893). Distributed in a discrete, punctate pattern with up to 3 loci per cell over the surface (PubMed:18800056). Anchored to the cell wall by sortase A (Probable).
