Collectins constitute a family of C-type lectins that recognize molecular patterns expressed on pathogens. Members of this glycoprotein family contain a N-terminal domain, a collagen-like domain, a neck region, and a C-terminal carbohydrate recognition domain (CRD). Collectins are typically secreted molecules, although CL-P1 is membrane bound and CL-L1 is found in the cytoplasm. Collectin kidney 1 (CL-K1), also known as collectin subfamily member 11 (COLEC11), is a 37kD collectin that circulates in the serum. It associates into disulfide-linked oligomers and preferentially interacts with fucose residues in a calcium-dependent manner. Mature mouse CL-K1 shares 94% and 98% amino acid sequence identity with human and rat CL-K1, respectively. Within the CRD, mouse CL-K1 shares 52% aa sequence identity with CL-L1 and 23%-32% aa sequence identity with collectins CL-P1, MBL, SP-A, and SP-D.
Catalog #C7549-85
DNA sequence encoding mouse CL-K1 (Gln 27-Leu 272; Accession # AAI0438) was fused to a 6x polyhistidine tag at the C-terminus. The protein was expressed in a mouse myeloma cell line, NS0.
ActivityMeasured by its ability to bind Alpha-L-Fucose.
ApplicationsSuitable for use in Western Blot. Other applications not tested.
Recommended DilutionsWestern Blot: As a result of glycosylation the recombinant mouse CL-K1 migrates as an ~33-38kD protein in SDS-PAGE under reducing conditions.
Optimal dilutions to be determined by the researcher.
