Annexin A13 shows high expression levels in specific human tissues, particularly in the gastrointestinal tract, bile ducts, gallbladder, renal tubules, and fallopian tubes, as summarized by The Human Protein Atlas [1]. It is also highly expressed in most renal cell carcinoma tissues [2]. Notably, annexin A13 is not expressed in normal epithelial cells but is found at moderate or high levels in tumor cells in 58.4% of colorectal cancer cases [3]. The protein is detected in epithelial cells in the colon and jejunum at the protein level [4]. The expression pattern of annexin A13 is tissue- and cell type-specific, with limited expression in other tissues [5]. Here is an image illustrating the expression of annexin A13 in human colorectal cancer tissues 6.
