Polymorphismi

According to some authors, 4 of the identified SERPIN11 transcripts contained coding sequences that could be distinguished by different combinations of single nucleotide polymorphisms (designated SERPINB11a, SERPINB11b, SERPINB11c, and SERPINB11d), and one contained a nonsense mutation introducing a premature stop codon in position 90 identified in the official genome sequence (SERPINB11f) (PubMed:17562709). The sequence displayed here corresponds to SERPINB11a.1 Publication

Caution

Mutations in the scaffold leading to either a stop codon instead of a Glu at position 90, an Arg instead of the well conserved Trp at position 188, or a Pro instead of Ser at position 303 lead to the loss of inhibitory activity.Curated
