@sjm41 Could you tag Todd Lowe? I can't seem to find his GitHub profile.

@sjm41 I wonder if we need to be differentiating further up the ontology? I'm trying to find another part of the ontology that differentiates types of sequence or sequence features...

> @sjm41 has provided a very good description on the issue. In addition to the distinct sequence features between cytosolic and mitochondrial tRNAs, plastids may have different genetic code in...

It looks like snoRNA (SO:0000275) and snRNA (SO:0000274) also mention cytological location in their definitions.

It seems like classifying tRNAs strictly using sequence features may present some challenges. I wonder if this is approaching the limit of SO's scope? Maybe we should be treating tRNA...

@sjm41 I agree that the current tRNA branch needs some work and initially I'm not opposed to the current proposal (isotypes of cytosolic/mitochondrial/plastid tRNAs) since it seems that it's what's...

When it comes to obsoleting @cmungall my training was pretty simple since we almost never do it. @davidwsant only obsoleted a term once before I started working with SO, but...

@sjm41 I've emailed Adam Frankish and asked him to confirm in this thread. If I don't hear back from him in a couple days we'll go ahead and obsolete.

Also @sjm41, just double checking that there isn't somewhere else that we need to be referring people to when it comes to this term?

@keilbeck There are a few PMIDs attached to these terms, but they're all over 20 years old. I see you're listed as a reference for methylation_guide_snoRNA_primary_transcript (SO:0000580). Were these branches...
