Protein attributes

Sequence length	255 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Subunit structure	Component of the small ribosomal subunit. Mature ribosomes consist of a small (40S) and a large (60S) subunit. The 40S subunit contains 32 different proteins (encoded by 56 genes) and 1 molecule of RNA (18S). The 60S subunit contains 46 different proteins (encoded by 81 genes) and 3 molecules of RNA (25S, 5.8S and 5S). Ref.5
Subcellular location	Cytoplasm. Ref.6
Post-translational modification	N-terminally acetylated by acetyltransferase NatA By similarity.
Miscellaneous	Present with 107000 molecules/cell in log phase SD medium. Ref.7 There are 2 genes for S1 in yeast.
Sequence similarities	Belongs to the ribosomal protein S3Ae family.
Caution	Was originally (Ref.1) thought to be MFT1, the mitochondrial fusion target protein.
