Surfactant protein D


Surfactant protein D, also known as SFTPD or SP-D, is a protein which in humans is encoded by the SFTPD gene.
SFTPD is an innate immune system collectin.

Interactions

Surfactant protein D has been shown to interact with DMBT1, and hemagglutinin of influenza A virus. Post-translational modification of SP-D i.e. S-nitrosylation switches its function.
