e1408ts : reverse kinker as adult variably Egl; L1 moves well; variable failures in postembryonic migration of Pn nuclei into ventral cord and (some alleles) embryonic migrations of hyp-7 hypodermal nuclei; all alleles are ts for Pn defect non-ts for hyp-7 defect; unmigrated Pn nuclei mostly fail to divide; adult male phenotype variable some can mate at 25x all can mate at 15x. ES3 ME3 (15x). NA11 (n331amber ts; e1409amber ts (suppressible only for hyp-7 defect)).

unc-83 encodes a KASH domain-containing transmembrane protein; during development, UNC-83 is required for nuclear migrations in P cells, hyp7 hypodermal precursors, and intestinal cells and thus, for ventral nerve cord development, locomotion, and vulval formation; specifically, UNC-83 functions to recruit kinesin and dynein motor complexes to the nuclear envelope to regulate the directionality and extent of nuclear migrations; UNC-83 localizes to the outer nuclear membrane and its localization is dependent upon the SUN domain of UNC-84, an inner nuclear membrane protein with which it interacts in vitro; UNC-83 and UNC-84 are thus proposed to link the nuclear lamina with the cytoskeleton to properly effect nuclear migrations.
Enables dynein light chain binding activity. Involved in several processes, including cellular localization; egg-laying behavior; and vulval development. Located in nuclear outer membrane. Expressed in several structures, including P1; P12; P2; P3; and P9. Used to study Emery-Dreifuss muscular dystrophy.
