Disruption phenotypei
Morpholino knockdown results in defects in eye deveopment, reduced expression of early eye marker genes rax, tbx3, six3 and pax6 and reduction of cell density at the neurula stage. Co-knockdown of nemp1b and ran elicits reduction of cell density and eye defects more significantly than the individual knockdown of either one.2 Publications

Expressioni
Developmental stagei
Expressed both maternally and zygotically. At the early gastrula stage, expressed mainly in the entire animal hemisphere. During neurulation, its expression becomes restricted to the anterior neuroectoderm. At the tailbud stage, expressed in various anterior regions including the anterior central nervous system (CNS), otic vesicles, and branchial arches.1 Publication
Interactioni
Subunit structurei
Interacts with banf1-a and banf1-b.
Interacts with ran-gtp.
