The locus of a human gene and its polypeptide product can both be identified using a single online resource:

Identifying Gene Loci
GenBank can be used to identify the specific location of a gene on any given chromosome
To identify a specific gene locus:
GenBank can also be used to identify the polypeptide product of any given gene.
To identify the polypeptide product of a gene:
GenBank can be used to identify the specific location of a gene on any given chromosome
To identify a specific gene locus:
- Change the search parameter from nucleotide to gene and type in the name of the gene of interest
- Choose the species of interest (i.e. Homo sapiens) and click on the link (under ‘Name / Gene ID’)
- Scroll to the ‘Genomic context’ section to determine the specific position of the gene locus
- A visual profile can be generated by clicking on ‘Map Viewer’ link and looking at the Ideogram on the left side
GenBank can also be used to identify the polypeptide product of any given gene.
To identify the polypeptide product of a gene:
- Change the search parameter from nucleotide to gene and type in the name of the gene of interest
- Choose the species of interest (i.e. Homo sapiens) and click on the link (under ‘Name / Gene ID’)
- The polypeptide product should be identified within the ‘Summary’ section
