n156 : adult hermaphrodites vulvaless ( > 99%) slightly small and fat HME1. ES2. Males very small scrawny rounded tail ME0. n156/Df is larval lethal. NA1.
[Labouesse M] n156 animals were injected together with rol-6(su1006) at 80 ng/microl and F2 rollers were picked and ability to lay eggs was scored as rescue (n156 animals are vulvaless and hence bag). The cosmids were injected at a concentration of 10 ng/microlitre or less. Further subcloning showed a 9 kb fragment from K06E5 to be sufficient to rescue n156.

lin-26 encodes a zinc-finger protein that shares a unique C2H2 motif together with LIR-1, LIR-2, and LIR-3; during development, lin-26 activity is required for proper differentiation of non-neuronal ectodermal cells and the somatic gonad epithelium; LIN-26 is expressed in many different cell types including the rectal rep, somatic gonad, glial, and hypodermal cells; ectopic LIN-26 expression during embryogenesis induces epithelial-like cell fates suggesting that LIN-26 is sufficient for epithelial differentiation.
Enables RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Involved in several processes, including establishment or maintenance of epithelial cell apical/basal polarity; tissue development; and vulval development. Located in nucleus. Expressed in several structures, including Z2; epithelial cell; germ line; gonad; and somatic gonad precursor.
