| Function | Branching enzyme that converts linear into branched poly-N-acetyllactosaminoglycans. Introduces the blood group I antigen during embryonic development. It is closely associated with the development and maturation of erythroid cells. The expression of the blood group I antigen in erythrocytes is determined by isoform C. |
| Subcellular Location | Golgi apparatus membrane {ECO:0000250}; Single-pass type II membrane protein {ECO:0000250}. |
| Tissue Specificity | In the adult, highly expressed in prostate and to a lesser extent in small intestine and colon. Barely detected in heart, brain, kidney and pancreas. No expression in placenta, lung, liver, skeletal muscle, spleen, thymus, testis, ovary and peripheral blood leukocytes. In fetus, highly expressed in brain and to a lesser extent in lung and kidney. Barely detected in liver. {ECO:0000269|PubMed:12424189, ECO:0000269|PubMed:9405606}. |
