Interactioni
Subunit structurei
Monomer (37LRP) and homodimer (67LR).
Component of the small ribosomal subunit. Mature ribosomes consist of a small (40S) and a large (60S) subunit. The 40S subunit contains about 33 different proteins and 1 molecule of RNA (18S). The 60S subunit contains about 49 different proteins and 3 molecules of RNA (28S, 5.8S and 5S).
Interacts with RPS21.
Interacts with several laminins including at least LAMB1.
Interacts with MDK. The mature dimeric form interacts with PPP1R16B (via its fourth ankyrin repeat).
Interacts with PPP1CA only in the presence of PPP1R16B.
