SFTPD - surfactant protein D Gene

Also Known as SP-D; PSP-D; SFTP4; COLEC7

Species: Homo sapiens

Gene Type: protein coding

Gene ID: 6441

About SFTPD

Cytogenetic location: 10q22.3 Genomic coordinates (GRCh38): 10:79,937,740-79,982,383 (from NCBI)

This gene has 4 transcripts (splice variants), 163 orthologues and 4 paralogues. Restricted expression toward lung (RPKM 293.0).

Summary

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]
