Function
TP4A1_HUMAN Protein tyrosine phosphatase which stimulates progression from G1 into S phase during mitosis. May play a role in the development and maintenance of differentiating epithelial tissues. Enhances cell proliferation, cell motility and invasive activity, and promotes cancer metastasis.[1] [2] [3]

Publication Abstract from PubMed
The PRL phosphatases, which constitute a subfamily of the protein tyrosine phosphatases (PTPs), are implicated in oncogenic and metastatic processes. Here, we report the crystal structure of human PRL-1 determined at 2.7A resolution. The crystal structure reveals the shallow active-site pocket with highly hydrophobic character. A structural comparison with the previously determined NMR structure of PRL-3 exhibits significant differences in the active-site region. In the PRL-1 structure, a sulfate ion is bound to the active-site, providing stabilizing interactions to maintain the canonically found active conformation of PTPs, whereas the NMR structure exhibits an open conformation of the active-site. We also found that PRL-1 forms a trimer in the crystal and the trimer exists in the membrane fraction of cells, suggesting the possible biological regulation of PRL-1 activity by oligomerization. The detailed structural information on the active enzyme conformation and regulation of PRL-1 provides the structural basis for the development of potential inhibitors of PRL enzymes.
Trimeric structure of PRL-1 phosphatase reveals an active enzyme conformation and regulation mechanisms.,Jeong DG, Kim SJ, Kim JH, Son JH, Park MR, Lim SM, Yoon TS, Ryu SE J Mol Biol. 2005 Jan 14;345(2):401-13. PMID:15571731[4]
