Summaries for SFTPD Gene

Entrez Gene Summary for SFTPD Gene

  • The protein encoded by this gene is part of the innate immune response, protecting the lungs against inhaled microorganisms and chemicals. The encoded protein may also be involved in surfactant metabolism. [provided by RefSeq, Jul 2015]

GeneCards Summary for SFTPD Gene

SFTPD (Surfactant Protein D) is a Protein Coding gene. Diseases associated with SFTPD include Extrinsic Allergic Alveolitis and Wilson-Mikity Syndrome. Among its related pathways are Bacterial infections in CF airways and Defective CSF2RA causes pulmonary surfactant metabolism dysfunction 4 (SMDP4). Gene Ontology (GO) annotations related to this gene include carbohydrate binding. An important paralog of this gene is MBL2.

UniProtKB/Swiss-Prot for SFTPD Gene

  • Contributes to the lungs defense against inhaled microorganisms, organic antigens and toxins. Interacts with compounds such as bacterial lipopolysaccharides, oligosaccharides and fatty acids and modulates leukocyte action in immune response. May participate in the extracellular reorganization or turnover of pulmonary surfactant. Binds strongly maltose residues and to a lesser extent other alpha-glucosyl moieties.

Post-translational modifications for SFTPD Gene

  • Hydroxylation on proline residues within the sequence motif, GXPG, is most likely to be 4-hydroxy as this fits the requirement for 4-hydroxylation in vertebrates.
  • S-nitrosylation at Cys-35 and Cys-40 alters the quaternary structure which results in a pro-inflammatory chemoattractive signaling activity with macrophages.
  • The N-terminus is blocked.
  • Glycosylation at posLast=9090
