LRRC15 (Leucine-Rich Repeat Containing 15) is a Protein Coding gene. 2 alternatively spliced human isoforms have been reported. The tumor antigen 15-leucine-rich repeat-containing membrane protein (LRRC15) is a transmembrane protein demonstrated to play important roles in cancer. LRRC15 is highly expressed in multiple solid tumor indications with limited normal tissue expression. It was expressed on stromal fibroblasts in many solid tumors (e.g., breast, head, and neck, lung, pancreatic) as well as directly on a subset of cancer cells of mesenchymal origin (e.g., sarcoma, melanoma, glioblastoma). The tumor antigen LRRC15, which is frequently overexpressed in multiple tumor types, as a repressor of cell death due to adenoviral p53.
