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 | The Rho GTPases, Cdc42 and Rac1, play critical roles in cell migration by integrating cell-substrate adhesion and actin polymerization. PARVB/affixin appears to participate in the activation of Rac and Cdc42 by associating with alpha PIX through its CH1 domain (Mishima et al., 2004; Rosenberger et al., 2005). This activity of PARVB/affixin could promote the polymerization of actin through the activation of downstream effectors of Rac1/Cdc42, including WASP-Arp2/3 and Mena/VASP. Alpha-PIX, ILK and PARVB can be found at the leading edge of spreading cells (Rosenberger et al., 2005 ), and it is likely that activation of Rac1 and Cdc42 at the lamellipodia in some cells is stimulated by interactions of aPIX with PARVB and regulated by interaction of ILK and PARVB (see Sepulveda and Wu, 2005 ). |
