Additional cross-species homologs
Sequence homologs in species beyond Ensembl Compara’s model organisms, by Diamond local protein alignment (% sequence identity; best hit per species). Lower-identity rows are more distant homologs. The matched accessions’ gene symbols aren’t in biobtree yet, so each row shows the UniProt accession.

Genomic neighbors (locus context)
Genes flanking this one on the chromosome (NCBI/Entrez gene neighborhood). Positional context only — some neighbors share regulatory elements (bidirectional promoters, antisense/overlapping transcripts), but chromosomal adjacency is not itself a functional relationship (see Interactions for that).
