Protein names


Protein function

This protein recognizes C4b and C3b fragments that condense with cell-surface hydroxyl or amino groups when nascent C4b and C3b are locally generated during C4 and c3 activation. Interaction of daf with cell-associated C4b and C3b polypeptides interferes with their ability to catalyze the conversion of C2 and factor B to enzymatically active C2a and Bb and thereby prevents the formation of C4b2a and C3bBb, the amplification convertases of the complement cascade.; (Microbial infection) Acts as a receptor for coxsackievirus A21, coxsackieviruses B1, B3 and B5 . Acts as a receptor for human enterovirus 70 and D68 (Probable) . Acts as a receptor for human echoviruses 6, 7, 11, 12, 20 and 21 .

Protein tissue specificity

Expressed on the plasma membranes of all cell types that are in intimate contact with plasma complement proteins. It is also found on the surfaces of epithelial cells lining extracellular compartments, and variants of the molecule are present in body fluids and in extracellular matrix.

Protein sequence and domain

The first Sushi domain (SCR1) is not necessary for function. SCR2 and SCR4 provide the proper conformation for the active site on SCR3 (By similarity).Belongs to the receptors of complement activation (RCA) family.; Contains 4 Sushi (CCP/SCR) domains.

Protein post-translational modifications

The Ser/Thr-rich domain is heavily O-glycosylated.

Protein cellular localization

Isoform 1: Cell membrane; Single-pass type I membrane protein.; Isoform 2: Cell membrane; Lipid-anchor, GPI-anchor.; Isoform 3: Secreted .; Isoform 4: Secreted .; Isoform 5: Secreted .; Isoform 6: Cell membrane ; Lipid-anchor, GPI-anchor .; Isoform 7: Cell membrane ; Lipid-anchor, GPI-anchor .


This gene encodes a protein involved in the regulation of the complement cascade. The encoded glycoprotein is also known as the decay-accelerating factor (DAF); binding of DAF to complement proteins accelerates their decay, disrupting the cascade and preventing damage to host cells. Antigens present on the DAF glycoprotein constitute the Cromer blood group system (CROM). Two alternatively spliced transcripts encoding different proteins have been identified. The predominant transcript encodes a membrane-bound protein expressed on cells exposed to plasma component proteins but an alternatively spliced transcript produces a soluble protein present at much lower levels. Additional, alternatively spliced transcript variants have been described, but their biological validity has not been determined. [provided by RefSeq, Jul 2008]
