Collectin liver 1 (CL-L1) show very similar carbohydrate selectivity as MBL. Two other discovered collectins include collectin placenta 1 (CL-P1) and collectin kidney 1 (CL-K1).
The identification of collectin liver 1 (CL-L1) reveals its similarity in carbohydrate binding properties to MBL. Furthermore, two other collectins, CL-P1 and CL-K1, have been identified as part of this group.
