Ashbya gossypii      His-Based PTP/TULA


※ TULA family introduction

    TULA/STS contains two members, UBASH3A/TULA-1 and UBASH3B/TULA-2. Sequence analysis shows that they share a conserved multidomain structure which contains an N-terminal ubiquitin-association domain, followed by a Src-homology 3 domain, and a C-terminal phosphatase domain. TULA/STS shows tyrosine phosphatase activity toward para-nitrophenyl phosphate, phosphotyrosine peptides and phosphoprotein ZAP70, Syk and certain Src family members. TULA/STS is distinct from other PTP which uses a cysteine residue as a catalytic residue (1). TULA/STS also belongs to the histidine phosphatase superfamily, that shares a conserved catalytic core centred on a histidine which is phosphorylated during the course of the reaction (2).
