class III signal peptide protein, archaeosortase D/PIP-CTERM system
Members of this protein family are short proteins that consist largely of the archaeal class III signal peptide (see pfam04021). Members are encoded in a gene cassette between archaeosortase D (TIGR04175) and its PIP-CTERM target protein (TIGR04173).
