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.

commentFUNCTION Component of the pre-T-cell receptor complex (composed of PTCRA, TCRB and the CD3 complex) that has a crucial role in early T-cell development, particularly alpha-beta T cell differentiation.SUBUNIT Heterodimer with TCRB; disulfide linked. This heterodimer assembles with CD3 proteins into a signaling-competent pre-T-cell receptor complex. Interacts with RHBDD1 (PubMed:22795130).SUBCELLULAR LOCATION Expressed in immature but not mature T-cells. Also found in CD34+ cells from peripheral blood, CD34+ precursors from umbilical cord blood and adult bone marrow.DEVELOPMENTAL STAGE Expressed in fetal life in CD34+ progenitors present in the liver at 18 weeks of gestation but is absent in CD34+ precursors from fetal bone marrow at any developmental stage up to 22 weeks.DISEASE Disease susceptibility is associated with variants affecting the gene represented in this entry.
