Predicted to enable adenylylsulfate kinase activity and sulfate adenylyltransferase (ATP) activity. Predicted to be involved in 3'-phosphoadenosine 5'-phosphosulfate biosynthetic process and sulfate assimilation. Predicted to act upstream of or within blood coagulation and bone development. Predicted to be located in cytosol. Human ortholog(s) of this gene implicated in spondyloepimetaphyseal dysplasia, Pakistani type. Orthologous to human PAPSS2 (3'-phosphoadenosine 5'-phosphosulfate synthase 2). [provided by Alliance of Genome Resources, Apr 2022]
