polyA_signal_sequence

SO:0000551

Definition: The recognition sequence necessary for endonuclease cleavage of an RNA transcript that is followed by polyadenylation; consensus=AATAAA.

Comments and references

Moved from transcription_regulatory_region (SO:0001679) to transcriptional_cis_regulatory_region (SO:0001055) by Dave Sant on Feb 11, 2021 when transcription_regulatory_region was merged into transcriptional_cis_regulatory_region to be consistent with GO and reduce redundancy as part of the GREEKC consortium. See GitHub Issue #527.

Change history

This timeline summarizes changes identified in SO’s GitHub commit history, including updates to labels, definitions, parent terms, synonyms, subsets, and obsoletion status. It is a best-effort reconstruction and may not include every change to a term. Since only history from GitHub is included at the moment, any term added before the migration from SVN to Git will show as being created in 2016. This will be addressed once SVN history is incorporated.
