UniProtKB - Q7ZU80 (LNPA_DANRE)
Endoplasmic reticulum junction formation protein lunapark-A
lnpka
Functioni
Endoplasmic reticulum (ER)-shaping membrane protein that plays a role in determining ER morphology. Involved in the stabilization of nascent three-way ER tubular junctions within the ER network. May also play a role as a curvature-stabilizing protein within three-way ER tubular junction network (By similarity).
