6FIN, also called DDR1 (Discodein Domain Receptor 1), is a receptor of the collagen.

Function

6 FIN is part of the RTKs family (Receptor Tyrosyne Kinases) which play a key role in the communication of cells with their microenvironment. These molecules are involved in the regulation of cell growth, differentiation and metabolism. The protein encoded by this gene is a RTK that is widely expressed in normal and transformed epithelial cells and is activated by various types of collagen.

6FIN is a transferase, so it is an Enzym which catalyses the transfer reaction of a functional group from a donor molecule to an acceptor one.

The inhibition of this protein

Disease

The binding of the collagen thanks to DDR1 (fibrosis) impacts several organs: it disrupts normal organs architectur and leads to organ function loss. The

Relevance

DDR1 is the subject for the development of novel antifibrotic medications. The inhibition of this protein prevents the diseases progression because it prohibits the link between the collagen and the cell. The inhibition of the DDR1 can stop or reduces the uncontrolled process characterised by the progressive accumulation of extra cellular matrix(ECM), mainly collagen.

Structural highlights

The DDR1 is a protein of 78.1kDa.
