Protein kodiran ovim genom spada upljuvačne proteine bogate prolinom. Ovaj i pet drugih gena koji također kodiraju pljuvačni proteine bogate prolinom (PRP), kao i gen koji kodira suznu žlijezdu PRP, čine PRP genski klaster u regiji 12p13 hromosoma 12.

PRB4 se posttranslacijski cijepa na tri različita zrela peptida:

• Protein N1
• Glikozilirani protein A
• Peptid P-D (poznat i kao Peptid IB-5 bogat prolinom)

Aminokiselinska sekvenca

Dužina polipeptidnog lanca je 310 aminokiselina, a molekulska težina 31 326 Da.
