Human CLEC4C/CD303/DLEC/BDCA2 Protein, ECD (Extracellular Domain), Fc-fusion, Biotinylated, Recombinant

CLEC4C (C-type lectin domain family 4 member C) or CD303, is a single-pass type II transmembrane protein that belongs to a the C-type lectin/C-type lectin-like domain (CTL/CTLD) superfamily.  Members of this superfamily share a common protein fold and have diverse functions, such as cell adhesion, cell-cell signalling, glycoprotein turnover, and roles in inflammation and immune response. CLEC4C contains 1 C-type lectin domain in the extracellular region and may play a role indendritic cell function.  It is expressed in immature monocyte-derived dendritic cells (iMDDC).  Its expression is significantly down-regulated upon maturation with LPS but not with TNF-alpha. CLEC4C may be involved in antigen-capturing by targeting ligand into antigen processing and peptide-loading compartments for presentation to T-cells. CLEC4C may mediate potent inhibition of induction of IFN-alpha/beta expression in plasmacytoid dendritic cells. It may also act as a signaling receptor that activates protein-tyrosine kinases and mobilizes intracellular calcium.

Gene Symbol: CLEC4C; DLEC; HECL; BDCA2; CD303; CLECSF7; CLECSF11; PRO34150
