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 | Kazrin (KAZN) is an evolutionarily-conserved cytoplasmic and nuclear protein that was identified as a binding partner of periplakin (PPL), a component of epidermal desmosomes (DS) and the cornified envelope (CE) (Groot et al. 2004). Kazrin has at least 5 different isoforms. Overexpression of the short isoform kazrinE stimulates the terminal differentiation of cultured human keratinocytes and is associated with a reduction in F-actin content, disruption of DS assembly, and changes in cell shape. Overexpression of activated RhoA rescues the effects on cell shape and adhesion. Conversely, knockdown of the longest isoform kazrinA impairs terminal differentiation, independently of RhoA activity (Sevilla et al. 2008a). KazrinE colocalizes with stabilized microtubules in differentiating keratinocytes (Nachat et al. 2009). All KAZN isoforms can form complexes with one another (Nachat et al. 2009), suggesting that like periplakin and envoplakin, it may form part of the cortical scaffold that integrates the actin cytoskeleton with DS (Ruhrberg et al. 1997, Kalinin et al. 2001, Groot et al. 2004). In Xenopus embryos, depletion of endogenous KAZN results in striking defects in axial elongation, muscle and notochord differentiation, and epidermal morphogenesis. These effects are believed to be due to disruption of cell-cell junctions (Sevilla et al. 2008b, Cho et al. 2010). However, mice with a knockout that removes exons 5-15 of KAZN had normal epidermal morphogenesis and homeostasis (Chhatriwala et al. 2012). |
