ColPTMScape: An open access knowledge base for tissue-specific collagen PTM maps

[Display omitted] •First dedicated knowledge base, ColPTMScape for collagen PTMs.•Information on the site-specificity and occupancy of collagen prolyl 3-hydroxylation in different tissue and species.•Consolidated site-specific knowledge of collagen lysyl-hydroxylation and O-glycosylation.•ColPTMScape would contribute to the larger matrix biology community. Collagen is a key component of the extracellular matrix (ECM). In the remodeling of ECM, a remarkable variation in collagen post-translational modifications (PTMs) occurs. This makes collagen a potential target for understanding extracellular matrix remodeling during pathological conditions. Over the years, scientists have gathered a huge amount of data about collagen PTM during extracellular matrix remodeling. To make such information easily accessible in a consolidated space, we have developed ColPTMScape (https://colptmscape.iitmandi.ac.in/), a dedicated knowledge base for collagen PTMs. The identified site-specific PTMs, quantitated PTM sites, and PTM maps of collagen chains are deliverables to the scientific community, especially to matrix biologists. Through this knowledge base, users can easily gain information related to the difference in the collagen PTMs across different tissues in different organisms.
