How can one find the mouse ortholog at Ensemble, without doing a BLAST search. Ans. From the Ensembl human genome browser, search for the SSBP4 gene.

3. It returns Ensembl Gene: ENSG00000130511 (RefSeq NM_032627.2). Following the link to GeneView in the Orthologue Predication section are the results of sequence comparison between the human gene and genes from other organisms. The mouse gene ENSMUSG00000070003 is a best reciprocal hit to the human. This mouse gene (growth differentiation factor 15) is a putative ortholog of the human SSBP4 corresponding to RefSeq. NM_133772.1 (see the Similarity Section).
