Glycan Function Workshop at SfG 2023

The second "Workshop on Glycan Function Annotation," entitled "Defining Glycan Functions" will be held on November 4th at Hilton Waikoloa Village Resort in Kona on the big island of Hawaii, just prior to the 2023 annual meeting of the Society for GlycoBiology. The workshop is organized and chaired by Dr. Michael Tiemeyer and Dr. René Ranzinger from the Complex Carbohydrate Research Center and is sponsored by the GlyGen project with the support of NIH. A select group of glycobiology experts have been invited to participate in discussions and contribute their ideas for developing a framework of terms and concepts relating glycan functions to glycan structural features, motifs, and patterns.

Workshop Goals

This workshop builds on the results of the first "Workshop on Glycan Function Annotation" which was held in Padova, Italy, May 2023 in association with this year’s annual International BioCuration meeting. The first workshop brought together interested developers and leaders of international bioinformatics platforms to discuss what kinds of glycoscience data were currently available or were desirable for sharing across platforms, leading to concrete suggestions for improving the visibility and impact of glycan, glycosylation, and glycoconjugate data.

Among the recommendations of the first workshop was a proposal that the bioinformatics community would benefit from the organization of a second workshop that could harvest input from experts in glycan functions. It was anticipated that such experts could provide useful landmarks in the rapidly expanding terrain of functional glycobiology data that could guide the development of useful knowledgebases and cross-references across datatypes. With the collaborative input of data scientists, such landmarks could subsequently be developed into a glycan function ontology, similar to “GO” annotations for gene product functions. A glycan function ontology would provide a potentially powerful framework for connecting glycoscience data to many mainstream big data resources.

Expected deliverables from the upcoming Kona workshop include:

Robust discussion and subsequent documentation that establishes some level of consensus on well-supported glycan functions.
Discussion and documentation of potential hierarchical relationships between glycan functions.
Discussion and documentation that connects functions to explicit glycan structures, structural motifs, features, or patterns whenever possible.
Discussion and documentation that highlights where ambiguities exist in connecting glycan structures and functions.
Discussion and documentation of proposals for annotating glycan functions that are independent of the carrier to which they are attached or are specific for the carrier and perhaps the site on the carrier to which they are attached (autonomous vs. non-autonomous functions).

To provide structure for the workshop, five general areas of glycan function have been chosen for framing discussions. However, the organizers expect that the boundaries of these areas are porous; we will proceed as best we can to achieve the goals. We anticipate that a successful workshop will culminate in a shared-authorship manuscript which summarizes our deliberations for community consideration and comment.
