Submaxillary Gland Androgen Regulated Protein 3A (SMR3A)

hSMR3A as a marker for patients with erectile dysfunction.hSMR3A can act as a marker for erectile dysfunction associated with diabetic and nondiabetic etiologies.

The nucleotide sequence of gene PBI, the putative translational product of which is homologous to salivary proline-rich protein P-B, has been determined. PBI is 6.4 kb long and contains 3 exons. The P-B1 precursor is composed of 134 amino acid residues including 22 residues of signal sequence, 23 residues of N-terminal sequence, five repeating units of 13 to 14 residues and 22 residues of C-terminal sequence. The signal sequence of this precursor is identical with that of the P-B precursor.
