Feature keyPosition(s)DescriptionActionsGraphical viewLength
<p>This subsection of the ‘Sequence’ section describes the sequence of naturally occurring alternative protein isoform(s). The changes in the amino acid sequence may be due to alternative splicing, alternative promoter usage, alternative initiation, or ribosomal frameshifting. The information stored in this subsection is used to automatically construct alternative protein sequence(s) for display.<p><a href='/help/var_seq' target='_top'>More...</a></p>Alternative sequenceiVSP_03686535Missing in isoform 2. 1 Publication1
