Transthyretin-like family protein [Caenorhabditis elegans]

Protein Classification

transthyretin-like family protein( domain architecture ID 10470959)

transthyretin-like family protein similar to Caenorhabditis elegans transthyretin-like protein 52 (TTR-52) that functions as a bridging molecule that mediates recognition and engulfment of apoptotic cells by cross-linking the surface-exposed phosphatidylserine with the extracellular domain of the phagocyte receptor ced-1

34-110 2.50e-33

Transthyretin-like family; TTR-52 was called family 2 in, and has weak similarity to transthyretin (formerly called pre-albumin) which transports thyroid hormones. The specific function of this protein is as a bridging molecule in apoptosis cross-linking dying cells to phagocytes. TTR-52 bridges by cross-linking surface-exposed phosphatidylserine (PtdSer) on apoptotic cells to the CED-1 receptor, a transmembrane receptor, on phagocytes. TTR-52 has an open beta-barrel-like structure.

33-74 3.00e-03

Domain of unknown function (DUF6795); This domain, mainly found in bacteria and eukaryotes, is functionally uncharacterized. This domain is approximately 100 amino acids in length and, based on structure prediction and overlaps with other families, belongs to the transthyretin superfamily. It is likely to have a seven stranded beta sandwich fold.
