About ITIH1

Cytogenetic location: 3p21.1 Genomic coordinates (GRCh38): 3:52,777,599-52,792,068 (from NCBI)

This gene has 12 transcripts (splice variants), 102 orthologues and 11 paralogues. Restricted expression toward liver (RPKM 383.5).

Summary

This gene encodes a member of the inter-alpha-trypsin inhibitor family of proteins. Alternative splicing results in multiple transcript variants, at least one of which encodes a preproprotein that is proteolytically processed to generate the heavy chain of the inter-alpha-trypsin inhibitor complex, which is secreted by hepatocytes into the blood. The heavy chain also interacts with hyaluronan, and this interaction may play a role in ovulation and fertilization, and has been implicated in multiple inflammatory diseases. This gene is present in a gene cluster on chromosome 3. [provided by RefSeq, Nov 2015]
