Functioni

Plays an important role in targeting the monocarboxylate transporters SLC16A1, SLC16A3 and SLC16A8 to the plasma membrane. Plays pivotal roles in spermatogenesis, embryo implantation, neural network formation and tumor progression. Stimulates adjacent fibroblasts to produce matrix metalloproteinases (MMPS). Seems to be a receptor for oligomannosidic glycans. In vitro, promotes outgrowth of astrocytic processes.1 Publication

Expressioni

Tissue specificityi

Essentially found in lymphocytes. Also present in various immature cells, endothelia and cells with excitable membranes.

Developmental stagei

In uterus during peri-implantation period strongly expressed in the luminal epithelium on day 1 of pregnancy and gradually decreased to a basal concentration from day 3 to day 5 of pregnancy. Strongly expressed in the implanting blastocyst and primary decidua on day 6 of pregnancy.1 Publication

Inductioni

By activation of lymphocytes by mitogens. By estrogen in the uterine epithelium of ovariectomized animals.1 Publication

Interactioni

Subunit structurei

Forms homooligomers in a cis-dependent manner on the plasma membrane. Forms a complex with MMP1 at the tumor cell surface (By similarity). Interacts with AJAP1, ATP1B2, MAG and L1CAM (By similarity). Interacts with SLC16A1, SLC16A7 and SLC1A3; probably a BSG dimer is associated with a monocarboxylate transporter dimer. Interacts with PPIL2; regulates BSG transport to the cell membrane.By similarity2 Publications
