How to check the type of identifier from ensembl?

Question

[Joseph Hughes]

When creating a homology adaptor, the homology members that are returned can either be protein ids or transcript ids. Is there a way of determining what type of ID is returned?

In more general terms, if I have an ensembl ID, is there a way to check whether this ID is for a transcript, gene, protein, genetree etc...

ENSG - geneid ENST - transcriptid ENSP - proteinid

EagleEye is right, but if you're wanting to code it, you could use the lookup endpoint on the REST API. If you're using the Perl API, the registry has a get_species_and_object_type method.
