nomenclature changes

01/15/2015 Human name has changed for Entrez Gene: 219959. From olfactory receptor, family 1, subfamily S, member 1 to olfactory receptor, family 1, subfamily S, member 1 (gene/pseudogene)

3/4/2022 removed ‘(gene/pseudogene)’ from gene name as human OR1S1 gene has validated gene type as ‘protein coding’, and other orthologs are also validated protein coding genes

summary for human OR1S1 from NCBI

Olfactory receptors interact with odorant molecules in the nose, to initiate a neuronal response that triggers the perception of a smell. The olfactory receptor proteins are members of a large family of G-protein-coupled receptors (GPCR) arising from single coding-exon genes. Olfactory receptors share a 7-transmembrane domain structure with many neurotransmitter and hormone receptors and are responsible for the recognition and G protein-mediated transduction of odorant signals. The olfactory receptor gene family is the largest in the genome. The nomenclature assigned to the olfactory receptor genes and proteins for this organism is independent of other organisms. This olfactory receptor gene is a segregating pseudogene, where some individuals have an allele that encodes a functional olfactory receptor, while other individuals have an allele encoding a protein that is predicted to be non-functional.

orthology

Note that NCBi acknowledges that "The nomenclature assigned to the olfactory receptor genes and proteins for this [humans] is independent of other organisms", so the Xenopus or1s1 is very unlikely to be a true ortholog of human OR1S1.
