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.

textLipid droplets (LDs) are cytosolic structures found in all eukaryotes, comprising a monolayer of phospholipids surrounding a core of uncharged lipids such as triglyceride (TAG) and sterol esters. They play an important role in both cellular physiology and disease. LD formation involves the partitioning of neutral lipids from their site of synthesis at the endoplasmic reticulum (ER) to the cytosol. The fat storage-inducing transmembrane proteins 1 (FITM1) belong to an evolutionarily-conserved gene family which mediates LD formation (Kadereit et al. 2008, Gross et al. 2011). FITM1 is an ER membrane associated protein that mediates binding (annotated here) and partitioning of TAGs into LDs (Gross et al. 2011, Miranda et al. 2014). FITM1 is expressed primarily in skeletal muscle whereas its paralog FITM2 is expressed primarily in adipose tissue, suggesting these proteins may have distinct functions (Gross et al. 2011).
