Laminin N-terminus α31 expression during development is lethal and causes widespread tissue-specific defects in a transgenic mouse model

Abstract: Alternative splicing of the laminin α3 gene gives rise to a netrin-like protein termed LaNt α31, the major structural feature of which is a laminin N-terminal domain. LaNt α31 is expressed across a wide range of tissues, is upregulated in cancers, and ex vivo and in vitro functional studies have indicated that this relatively unstudied protein influences wound repair, stem cell activity, and tumour progression via modifying matrix organisation. However, LaNt α31 functionality has never been investigated in viv… Show more

“…One LAMA3-derived alternative splice isoform, Laminin N terminus α31 (LaNt α31) has widespread expression in human tissues (Troughton et al, 2020b), is upregulated during wounding and corneal limbal stem cell activation (Barrera et al, 2018) and emerging data indicate that it can modulate LM organization in vitro (Troughton et al, 2020a). In vivo overexpression is embryonic lethal during development with tissue defects that resemble LM network disruption phenotypes (Sugden et al, 2020).…”
