CC -!- FUNCTION: [Irisin]: Contrary to mouse, may not be involved in the
CC beneficial effects of muscular exercise, nor in the induction of
CC browning of human white adipose tissue. {ECO:0000269|PubMed:24040023}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000269|PubMed:22237023};
CC Single-pass type I membrane protein {ECO:0000269|PubMed:22237023}.
CC Peroxisome membrane {ECO:0000250}; Single-pass type I membrane protein
CC {ECO:0000250}. Note=Imported in peroxisomes through the PEX5 receptor
CC pathway. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: [Irisin]: Secreted. Note=Detected in the blood of
CC individuals subjected to endurance exercise.
CC {ECO:0000269|PubMed:22237023}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=4;
CC Name=1;
CC IsoId=Q8NAU1-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q8NAU1-2; Sequence=VSP_032861, VSP_032862;
CC Name=3;
CC IsoId=Q8NAU1-3; Sequence=VSP_032860, VSP_032863;
CC Name=4;
CC IsoId=Q8NAU1-4; Sequence=VSP_032860;
CC -!- TISSUE SPECIFICITY: Widely expressed, with highest levels in heart.
CC Very low expression, if any, in colon, pancreas and spleen.
CC {ECO:0000269|PubMed:24040023}.
CC -!- INDUCTION: Has been shown to be up-regulated some twofold by muscular
CC exercise at the mRNA and protein level; this effect has been suggested
CC to be mediated by PPARGC1A (PubMed:22237023). However, up-regulation
CC upon exercise could not be reproduced, at least not at the mRNA level
CC (PubMed:24040023). {ECO:0000269|PubMed:22237023,
CC ECO:0000269|PubMed:24040023}.
CC -!- PTM: The extracellular domain is cleaved and released from the cell
CC membrane.
CC -!- PTM: N-Glycosylated. {ECO:0000250}.
CC -!- CAUTION: It is uncertain whether Met-1 or Met-76 is the initiator.
CC Transcript evidence available at present time points at Met-76. In this
CC short version of the protein, the signal peptide cannot be predicted
CC and the irisin peptide is severely truncated. The first initiation
CC codon corresponds to a non-AUG site, an N-terminal ATA codon. This
CC initiation codon has been annotated as it is in good Kozak context and
CC it is conserved in other primates, including gibbon, chimpanzee and
CC gorilla. Although the existence of such a form has not been
CC demonstrated in human, western blot analysis following endurance
CC exercise shows the presence of an irisin peptide of similar size in
CC human and mouse plasma (PubMed:22237023), suggesting the existence of
CC full-length irisin in human, at least in some tissues. However,
CC expression from Met-1 may be less efficient than that from Met-76
CC (PubMed:24040023). {ECO:0000305|PubMed:22237023,
CC ECO:0000305|PubMed:24040023}.
