About HTRA2

Cytogenetic location: 2p13.1 Genomic coordinates (GRCh38): 2:74,529,405-74,533,556 (from NCBI)

This gene has 17 transcripts (splice variants), 195 orthologues, 3 paralogues and is associated with 5 phenotypes. Ubiquitous expression in spleen (RPKM 12.3), bone marrow (RPKM 11.8) and 25 other tissues.

Summary

This gene encodes a serine protease. The protein has been localized in the endoplasmic reticulum and interacts with an alternatively spliced form of mitogen-activated protein kinase 14. The protein has also been localized to the mitochondria with release to the cytosol following apoptotic stimulus. The protein is thought to induce Apoptosis by binding the Apoptosis inhibitory protein baculoviral IAP repeat-containing 4. Nuclear localization of this protein has also been observed. Alternate splicing of this gene results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Mar 2016]
