=head1 NAME
Bio::SeqFeature::Gene::UTR - A feature representing an untranslated region
that is part of a transcriptional unit
=head1 SYNOPSIS
See documentation of methods
=head1 DESCRIPTION
A UTR is a Bio::SeqFeature::Gene::ExonI compliant object that is
non-coding, and can be either 5' or 3' in a transcript.

=head1 APPENDIX
The rest of the documentation details each of the object methods.
Internal methods are usually preceded with a _
=cut
# Let the code begin...
package Bio::SeqFeature::Gene::UTR;
use strict;
# Object preamble - inherits from Bio::Root::Root
use base qw(Bio::SeqFeature::Gene::Exon);
=head2 new
Title : new
Usage :
Function: We override the constructor here to set is_coding to false
unless explicitly overridden.
Example :
Returns :
Args :
=cut
sub new{
my ($caller, @args) = @_;
if(! grep { lc($_) eq '-is_coding'; } @args) {
push(@args, '-is_coding', 0);
}
my $self = $caller->SUPER::new(@args);
my ($primary, $prim) =
$self->_rearrange([qw(PRIMARY PRIMARY_TAG)],@args);
$self->primary_tag('utr') unless $primary || $prim;
return $self;
}
=head2 primary_tag
Title : primary_tag
Usage : $tag = $feat->primary_tag()
Function: Returns the primary tag for a feature,
eg 'utr5prime'. This method insures that 5prime/3prime information
is uniformly stored
Returns : a string
Args : none
=cut
sub primary_tag{
my $self = shift;
if(@_ && defined($_[0])) {
my $val = shift;
if ($val =~ /(3|5)/ ) {
$val = "utr$1prime";
} else {
$self->warn("Primary tag should indicate if this is 3 or 5'. ".
"Preferred text is 'utr3prime' or 'utr5prime'.");
}
unshift(@_,$val);
}
return $self->SUPER::primary_tag(@_);
}
