Query author contributions in Reactome
Reactome depends on collaboration between our curation team and outside experts to
assemble and peer-review its pathway modules. The integration of ORCID within Reactome
enables us to meet a key challenge with authoring, curating and reviewing biological
information by incentivizing and crediting the external experts that contribute their
expertise and time to the Reactome curation process. More information is available at
ORCID and Reactome.
If you have an ORCID ID that is not listed on this page, please
forward this information to us and we will update your Reactome pathway records.

| text | PTEN missense mutation that results in the substitution of arginine at position 130 with glutamine affects the conserved H-C-K/R-A-G-K-G-R sequence (corresponding to HCXXGXXR motif of protein tyrosine phosphatases) in the catalytic cleft of the PTEN phosphatase domain. The arginine residue in this motif, corresponding to R130 of human PTEN, is essential for catalysis (Barford et al. 1994, Lee et al. 1999). PTEN R130Q (Arg130Gln) mutant shows markedly decreased phosphoinositide phosphatase activity (Han et al. 2000). PTEN R130Q substitution is frequently found in endometrial cancer (Konopka et al. 2007). |
