Research Abstract

SgIGSF(spermatogenic immunoglobulin superfamily)/TSLC1(tumor suppressor in lung cancer-1)は、免疫グロブリン・スーパーファミリーに属する細胞膜1回貫通型の接着分子で、様々な細胞に発現しており、精子形成やシナプス形成など種々の機能を有するが、本分子の機能制御の仕組みについてはよくわかっていない。本研究課題では、SgIGSF/TSLC1の発現制御機構として転写調節(splicingによる分泌型分子の産生)と転写後調節(sheddingによる細胞外ドメイン断片の産生)が存在することを明らかにした。加えて、分泌型分子は細胞外に放出された後、神経突起上に発現する膜貫通型分子とtrans-ホモフィリックに結合することにより、神経突起の伸長方向の制御に関わることがわかった。
