Protein domain
A C-type lectin (CLEC ) is a type of carbohydrate-binding protein 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
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]
CLECs include:
CLEC1A , CLEC1B
CLEC2A , CLEC2B , CD69 (CLEC2C), CLEC2D , CLEC2L
CLEC3A , CLEC3B
CLEC4A , CLEC4C , CLEC4D , CLEC4E , CLEC4F , CLEC4G , ASGR1 (CLEC4H1), ASGR2 (CLEC4H2), FCER2 (CLEC4J), CD207 (CLEC4K), CD209 (CLEC4L), CLEC4M
CLEC5A
CLEC6A
CLEC7A
OLR1 (CLEC8A)
CLEC9A
CLEC10A
CLEC11A
CLEC12A , CLEC12B
CD302 (CLEC13A), LY75 (CLEC13B), PLA2R1 (CLEC13C), MRC1 (CLEC13D), MRC2 (CLEC13E)
CLEC14A
CLEC16A
CLEC17A
The "NK Cell lectin-like receptors" are a very closely related group:[ 10]
