How do I find a protein sequence for a specific Gene from a specific organism?

How to: Find transcript sequences for a gene

1. Search the Gene database with the gene name, symbol.
2. Click on the desired gene.
3. Click on Reference Sequences in the Table of Contents at the upper right of the gene record.

How do you identify Gene homologues?

Search the HomoloGene database with the gene name. If you know both the gene symbol and organism, use a query such as this: tpo[gene name] AND human[orgn]. If your search finds multiple records, click on the desired record. The homologous genes are listed in the top of the report.

How do you find the Gene sequence of a protein?

The protein sequence can also be found by clicking on the protein accession number in the Nucleotide record or in the RefSeq section of the Gene record.

How do you find Gene accession number?

How to: Find published information on a gene or sequence

1. Search the PubMed database of biomedical literature with the gene name, symbol or sequence accession number.
2. Search the Gene database with the gene name, symbol or sequence accession number.
3. Click on the desired gene.

How do you compare protein sequences between species?

​ 1). 1). The biological question being addressed by the comparative analysis will determine the appropriate level of nucleotide similarity (evolutionary distance) of the sequences and the alignment method used.

How do you get ortholog?

To find orthologs enter a gene symbol (e.g. RAG1) or a gene symbol combined with a taxonomic group (e.g. primate RAG1). Select the matching entry from the suggestions menu or you can select the orthologs option (e.g. Rag1 orthologs) to see all orthologs.

What is accession number in NCBI?

ACCESSION. The unique identifier for a sequence record. An accession number applies to the complete record and is usually a combination of a letter(s) and numbers, such as a single letter followed by five digits (e.g., U12345) or two letters followed by six digits (e.g., AF123456).

What is protein accession number?

An accession number in bioinformatics is a unique identifier given to a DNA or protein sequence record to allow for tracking of different versions of that sequence record and the associated sequence over time in a single data repository.

What is sequence retrieval system?

SRS (Sequence Retrieval System) is an information indexing and retrieval system designed for libraries with a flat file format such as the EMBL nucleotide sequence databank, the SwissProt protein sequence databank or the Prosite library of protein subsequence consensus patterns.
