CELE_C38D4.3, C38D4.3

mel-28 encodes a large (1,784-residue) protein required for nuclear envelope assembly; MEL-28 is highly divergent from, but orthologous to human AT-hook-containing transcription factor 1 (AHCTF1); MEL-28 is found in nuclear pore complexes (NPCs) during interphase, kinetochores early in mitosis, and chromatin later in mitosis; mel-28 mutants were first identified in a screen for genes involved in cell division in the early embryo; mel-28 mutants or mel-28(RNAi) animals have no (or poorly visible) pronuclei and nuclear morphology generally, along with a weak mitotic spindle, aberrant chromatin segregation, and abnormally distributed nuclear envelope (NE) proteins and NPCs; MEL-28 is needed for normal localization of LMN-1 and EMR-1, and appears to be a stable structural component of the NE; maternal MEL-28 is needed for embryonic development.
