Summaries for ITIH4 Gene

Entrez Gene Summary for ITIH4 Gene

  • The protein encoded by this gene is secreted into the blood, where it is cleaved by plasma kallikrein into two smaller forms. Expression of this gene has been detected only in liver, and it seems to be upregulated during surgical trauma. This gene is part of a cluster of similar genes on chromosome 3. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2009]

GeneCards Summary for ITIH4 Gene

ITIH4 (Inter-Alpha-Trypsin Inhibitor Heavy Chain Family, Member 4) is a Protein Coding gene. Diseases associated with ITIH4 include aids dementia complex and hypercholesterolemia, familial. GO annotations related to this gene include serine-type endopeptidase inhibitor activity and endopeptidase inhibitor activity. An important paralog of this gene is ITIH1.

UniProtKB/Swiss-Prot for ITIH4 Gene

  • Type II acute-phase protein (APP) involved in inflammatory responses to trauma. May also play a role in liver development or regeneration.

    Molecular mass:
    103357 Da
    Quaternary structure:
    • Interacts (via C-terminus) with DNAJC1 (via SANT 2 domain); this interaction protects ITIH4 against cleavage by kallikrein in vitro.
    Miscellaneous:
    • Possible biomarker for acute ischemic stroke (PubMed:19263524). Peptides derived from the proline-rich potentially active peptide (PRO_0000016542) may be biomarkers for a variety of disease states including breast cancer (PubMed:21137033).

Post-translational modifications for ITIH4 Gene

  • Cleaved by plasma kallikrein to yield 100 kDa and 35 kDa fragments, and the resulting 100 kDa fragment is further converted to a 70 kDa fragment
  • N- and O-glycosylated. In urine, O-linked glycosylation on threonine residues in the region from Thr-719 to Thr-725 consists of core 1 or possibly core 8 glycans. Mainly Hex(HexNAc)(2), but also some Hex(3)(HexNAc)(3). N-glycosylated but not O-glycosylated in plasma.
  • Glycosylation at Asn81, Asn207, Asn517, Asn577, and Thr720
