Isoform 2 dephosphorylates phosphorylated phytochromes, with a preference toward Pfr forms, and enhances phytochrome-mediated photoresponses, probably by enhancing their stability and their binding affinity for light signal transducers such as NDPK2. Can use para-nitrophenylphosphate (pNPP) as substrate.1 Publication

<p>This subsection of the ‘Sequence’ section lists the alternative protein sequences (isoforms) that can be generated from the same gene by a single or by the combination of up to four biological events (alternative promoter usage, alternative splicing, alternative initiation and ribosomal frameshifting). Additionally, this section gives relevant information on each alternative protein isoform.<p><a href='/help/alternative_products' target='_top'>More...</a></p> isoformsi produced by alternative splicing.

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
<p>The checksum is a form of redundancy check that is calculated
from the sequence. It is useful for tracking sequence updates.</p>
<p>It should be noted that while, in theory, two different sequences could
have the same checksum value, the likelihood that this would happen
is extremely low.</p>
<p>However UniProtKB may contain entries with identical sequences in case
of multiple genes (paralogs).</p>
<p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64)
using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1.
The algorithm is described in the ISO 3309 standard.
