! PomBase Reference Collection
!

! The PomBase reference collection is a set of abstracts that can be
! cited to support annotations. It is modeled on the GO reference
! collection (see http://www.geneontology.org/cgi-bin/references.cgi
! and http://www.geneontology.org/doc/GO.references)
!
! data fields for this file:
!
!  pb_ref_id: [mandatory; cardinality 1; PB_REF:nnnnnnn]
!  alt_id: [not mandatory; cardinality 0,1,>1; PB_REF:nnnnnnn]
!  title: [mandatory; cardinality 1; free text]
!  authors: [mandatory; cardinality 1; free text
!            but check whether GO ever switches to cardinality 1,>1 and one entry per author]
!  year: [mandatory, cardinality 1]
!  external_accession: [not mandatory; cardinality 0,1,>1; DB:id]
!  citation: [not mandatory; cardinality 0,1; use for published refs]
!  abstract: [mandatory; cardinality 1; free text]
!  comment: [not mandatory; cardinality 1; free text]
!  is_obsolete: [not mandatory; cardinality 0,1; 'true';
!            if tag is not present, assume that the ref is not obsolete
!            denotes a reference no longer used by the contributing database]
!

!  If another reference collection (e.g. another model organism
!  database) has a record that is equivalent to a PB_REF entry, the
!  database's internal ID should be included as an external_accession
!  for the corresponding PB_REF.

title: 
title: Protein modification annotation by manual transfer of experimentally-verified annotation data to orthologs based on curator judgment of sequence features.
authors: PomBase curators
year: 2015
abstract: 
Method for transferring PSI-MOD protein modification annotations to a protein-coding gene based on a curator's judgment of its similarity to a putative ortholog that has annotations that are supported by experimental evidence. Annotations are created when a curator judges that the protein sequence contains a match to a sequence region or motif that is known to be a consensus site for the modification, and when an ortholog has been identified and experimentally determined to have the modification.
