Phosphatase GeneID SpurP054

A pseudogene probably originates from SpurP111.

Though SpurP054 is fragmentary, it is different from other phosphatases in protein and genomic sequence. The closest sequence is SpurP111, which is 92% identity in protein sequence. By BLATing purple sea urchin genome at UCSC genome browser (assembly Baylor 2.1), it is distinct from SpurP111 in genomic sequence. It is therefore a locus different from SpurP111.

It has a sequence as below:

>Spur_SpurPTP-Un-4 id=SpurP054_AA CC1:CC1:PTP:PTP-unclassified [Strongylocentrotus purpuratus] NCSAGVGRTGTFITINCMIEMIEADEKIDVFNFINEMR

But, it can be extended in genomic sequence:

>Extended NCSAGVGRTGTFITINCMIEMIEADEKIDVFNFINEMR*RIAFMVQVQVIY

This is now a pseudogene, so I suggest it be classified as a pseudogene and as PTPRB-like.
