abstractText | A novel type II integral membrane protein has been identified in the course of screening for genes overexpressed in a mouse model of chronic myelogenous leukemia blast crisis. This new protein, designated NKCL, consists of a 210-amino acid polypeptide with a short, NH2- terminal cytoplasmic tail of 17 amino acids preceding a transmembrane domain and a COOH-terminal extracellular region. The COOH-terminal 132 amino acids bear typical features of the C-type animal lectin carbohydrate- recognition domain. The Nkcl gene is unique in that it maps just proximal to the region of the genome that encodes group V members of the C-type animal lectin family near the natural killer gene complex on mouse chromosome 6, but its protein product also has features of several group II C-type animal lectins, Most notably, it has a complete Ca2+-binding site 2, which forms part of the sugar-binding site in other members of the family, and binds mannose in a Ca2+-dependent manner. Moreover, its expression is not restricted to natural killer cells, as reported for the majority of group V lectins, Nkcl is expressed in pluripotent myeloid precursors, precursor and mature macrophages, and neutrophils. |
