== Publication Abstract from PubMed ==
SHP2 is an allosteric phosphatase essential for growth factor-mediated Ras activation. Germline mutations in SHP2 cause clinically similar LEOPARD and Noonan syndromes, two of several autosomal-dominant conditions characterized by gain-of-function mutations in the Ras pathway. Interestingly, Noonan syndrome SHP2 mutants are constitutively active, while LEOPARD syndrome SHP2 mutants exhibit reduced phosphatase activity. How do catalytically impaired LEOPARD syndrome mutants engender gain-of-function phenotypes? Our study reveals that LEOPARD syndrome mutations weaken the intramolecular interaction between the N-SH2 and phosphatase domains, leading to a change in SHP2's molecular switching mechanism. Consequently, LEOPARD syndrome SHP2 mutants bind upstream activators preferentially and are hypersensitive to growth factor stimulation. They also stay longer with scaffolding adapters thus prolonging substrate turnover, which compensates for the reduced phosphatase activity. The study provides a solid framework for understanding how individual SHP2 mutations cause diseases.

Disease

PTN11_HUMAN Defects in PTPN11 are the cause of LEOPARD syndrome type 1 (LEOPARD1) [MIM:151100. It is an autosomal dominant disorder allelic with Noonan syndrome. The acronym LEOPARD stands for lentigines, electrocardiographic conduction abnormalities, ocular hypertelorism, pulmonic stenosis, abnormalities of genitalia, retardation of growth, and deafness.[1] [2] [3] [4] [5] [6] [7] Defects in PTPN11 are the cause of Noonan syndrome type 1 (NS1) [MIM:163950. Noonan syndrome (NS) is a disorder characterized by dysmorphic facial features, short stature, hypertelorism, cardiac anomalies, deafness, motor delay, and a bleeding diathesis. Some patients with Noonan syndrome type 1 develop multiple giant cell lesions of the jaw or other bony or soft tissues, which are classified as pigmented villomoduolar synovitis (PVNS) when occurring in the jaw or joints. Note=Mutations in PTPN11 account for more than 50% of the cases. Rarely, NS is associated with juvenile myelomonocytic leukemia (JMML). NS1 inheritance is autosomal dominant.[8] [9] [10] [11] [12] [13] [14] [15] [16] [17] [18] [19] Defects in PTPN11 are a cause of juvenile myelomonocytic leukemia (JMML) [MIM:607785. JMML is a pediatric myelodysplastic syndrome that constitutes approximately 30% of childhood cases of myelodysplastic syndrome (MDS) and 2% of leukemia. It is characterized by leukocytosis with tissue infiltration and in vitro hypersensitivity of myeloid progenitors to granulocyte-macrophage colony stimulating factor.[20] Defects in PTPN11 are a cause of metachondromatosis (MC) [MIM:156250. It is a skeletal disorder with radiologic fetarures of both multiple exostoses and Ollier disease, characterized by the presence of multiple enchondromas and osteochondroma-like lesions.[21]

Function

PTN11_HUMAN Acts downstream of various receptor and cytoplasmic protein tyrosine kinases to participate in the signal transduction from the cell surface to the nucleus. Dephosphorylates ROCK2 at Tyr-722 resulting in stimulatation of its RhoA binding activity.[22] [23] [24]
