Sirtuin 4, also known as SIRT4, is a protein which in humans is encoded by the SIRT4 gene.[5][6]



Function


This gene encodes a member of the sirtuin family of proteins which are homologs of the Sir2 gene in budding yeast. Members of the sirtuin family are characterized by a sirtuin core domain and grouped into four classes. The functions of human sirtuins have not yet been fully determined; however, yeast sirtuin proteins are known to regulate epigenetic gene silencing and suppress recombination of rDNA.[7] Studies suggest that the human sirtuins may function as intracellular regulatory proteins with mono-ADP-ribosyltransferase activity.[5][7] The protein encoded by this gene is included in class IV of the sirtuin family.[6]


SIRT4 is a mitochondrial ADP-ribosyltransferase that inhibits mitochondrial glutamate dehydrogenase 1 activity, thereby downregulating insulin secretion in response to amino acids.[8] It has been shown that SIRT4 regulates fatty acid oxidation and mitochondrial gene expression in liver and muscle cells.[9]

I successfully done installation of jBPM Console, drawing business process asset in KIE process and starting the application are going well. And I tested according to reference.

In tutorial, they give the following link to make POST request. http://localhost:8090/rest/server/containers/business-application-kjar/processes/business-application-kjar.process/instances I do but I always get " 415 Unsupported Media Type " in every time.
