A C-type lectin (CLEC) is a type of carbohydrate-binding protein domain known as a lectin.[3] The C-type designation is from their requirement for calcium for binding.[4] Proteins that contain C-type lectin domains have a diverse range of functions including cell-cell adhesion, immune response to pathogens and apoptosis.[5][6]

Classification [ edit ]

Drickamer et al. classified C-type lectins into 7 subgroups (I to VII) based on the order of the various protein domains in each protein.[7] This classification was subsequently updated in 2002, leading to seven additional groups (VIII to XIV).[8] Most recently, three further subgroups were added (XV to XVII).[3]

Group Name Associated domains
I Lecticans EGF, Sushi, Ig and Link domains
II Asialoglycoprotein and DC receptors None
III Collectins None
IV Selectins Sushi and EGF domains
V NK - cell receptors None
VI Multi-CTLD endocytic receptors FnII and Ricin domains
VII Reg group None
VIII Chondrolectin, Layilin None
IX Tetranectin None
X Polycystin WSC, REJ, PKD domains
XI Attractin (ATRN) PSI, EGF and CUB domains
XII Eosinophil major basic protein (EMBP) None
XIII DGCR2 None
XIV Thrombomodulin, CD93, CD248, CLEC14A EGF domains [9]
XV Bimlec None
XVI SEEC SCP and EGF domains
XVII CBCP/Frem1/QBRICK CSPG repeats and CalX-beta domains

CLECs include:

The "NK Cell lectin-like receptors" are a very closely related group:[10]

Additional proteins containing this domain include:
