May play a role in the development of the nervous system such as in neurite outgrowth and elongation. May be involved in motor axon growth and guidance. Interacts with RABGGTB. Found in spleen, testis, prostate and fetal liver. Expression limited to vascular muscle of testis, smooth muscle of prostate stroma, heart muscle, skeletal muscle, crypts of small intestine, and red pulp of spleen. B lymphocytes express isoform 2 only; peripheral blood T lymphocytes express isoform 3 only; granulocytes and monocytes express neither isoform 2 nor isoform 3. During development of T lymphocytes, bone marrow progenitor cells express isoform 2 only; thymocytes at different stages of maturation express predominantly isoform 2 and weakly isoform 3, and mature thymocytes express only isoform 2. N-glycosylated. A protein of the expected size has been detected by antibody binding and Western blot in at least one of the analyzed tissues or cells. Produced by alternative promoter usage. Produced by alternative promoter usage. Produced by alternative splicing of isoform 2. Produced by alternative splicing of isoform 1. Chondrolectin
