Abstract:
To date, transcript variants of the nuclear envelope protein Nurim and their expression profiles in mice have never been elucidated. In this study, we determined that the primary Nurim variant a was abundantly expressed in mouse heart, liver, spleen and kidney. The protein level of isoform a is initiated at an early stage of heart formation and demonstrated a significant increase in expression throughout embryonic heart development. Interestingly, Nurim b is also up-regulated from E12.5 to E18.5 in different individuals. Our research represents the first report on alternative splicing variants of mouse Nurim and their differential expression profile during embryonic development. These studies suggest a potential role for Nurim in early heart morphogenesis and should help further elucidate the function of Nurim.
