UniProtKB - P38871 (SSP1_YEAST)
Protein
Sporulation-specific protein 1
Gene
SSP1
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Functioni
Involved in the pathway that organizes the shaping and sizing of the prospore membrane (PSM) during sporulation. May be required for the formation of ADY3 and DON1-containing protein coats at the leading edge of the PSMs during meiosis II.2 Publications
