Urine exosomal CP, observed to increase prior to proteinuria, makes it a potential urinary biomarker to diagnose early kidney disease.
Title: Urine exosomal ceruloplasmin: a potential early biomarker of underlying kidney disease.
This study found that CP was expressed on neurons and astrocytes in both cortex and basal ganglia after Intracerebral Hemorrhage.
Title: Brain Ceruloplasmin Expression After Experimental Intracerebral Hemorrhage and Protection Against Iron-Induced Brain Injury.
Data suggest beta-glucuronidase and bilitranslocase in vascular endothelium are involved in changes in endothelium-independent vaso-relaxation induced by dietary antioxidants; here, using in vitro studies with thoracic aorta rings in oxidative stress, glucuronides of dietary supplement antioxidant hydroxytyrosol (HT) are deconjugated by beta-glucuronidase before HT is taken up by vascular endothelium via bilitranslocase.
Title: Involvement of bilitranslocase and beta-glucuronidase in the vascular protection by hydroxytyrosol and its glucuronide metabolites in oxidative stress conditions.
these results suggest that genetically determined Cp levels can alter susceptibility to Crescentic glomerulonephritis through macrophage function and propose a new role for Cp in early macrophage activation.

Ferroportin 1 and CP colocalize in the rat brain.
Title: Ceruloplasmin is Involved in the Nigral Iron Accumulation of 6-OHDA-Lesioned Rats.
Cerebral ischemia inhibited ceruloplasmin expression in the cortex and hippocampus of rats. The decrease of Cp might be involved in iron deposition in neurons.
Title: An inhibition of ceruloplasmin expression induced by cerebral ischemia in the cortex and hippocampus of rats.
Data show there was no significant difference detected in hepatic and hippocampus iron levels in response to increased serum ceruloplasmin between control and copper-intoxicated rats.
Title: Hepatic and hippocampus iron status is not altered in response to increased serum ceruloplasmin and serum "free" copper in Wistar rat model for non-Wilsonian brain copper toxicosis.
FOX activity was present in rat cytosol, and was partly inhibited by anti-Heph antibody.
Title: Immunoreactive hephaestin and ferroxidase activity are present in the cytosolic fraction of rat enterocytes.
Liver copper loading increases metallation of the Cp protein, leading to increased production of the holo enzyme.
Title: Serum ceruloplasmin protein expression and activity increases in iron-deficient rats and is further enhanced by higher dietary copper intake.
Insulin downregulat CP mRNA levels and attenuates CP secretion in rat liver cells.
Title: Ceruloplasmin expression in rat liver cells is attenuated by insulin: role of FoxO transcription factors.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

mRNA and Protein(s)

NM_001270961.1 → NP_001257890.1 ceruloplasmin isoform 2 precursor

See identical proteins and their annotated locations for NP_001257890.1

Status: VALIDATED

Description

Transcript Variant: This variant (2) lacks an exon and contains two alternate 3' exons compared to variant 1. The resulting protein (isoform 2), which is longer and has a distinct C-terminus compared to isoform 1, is a glycosylphosphatidylinositol-anchored form.
