From French homologue, From Ancient Greek ὁμόλογος ("agreeing, of one mind"), equivalent to homo +‎ -log


  • As it turns out, a very similar gene, Atonal homolog 1, controls the development secretory cells in the lining of the colon in both humans and mice — and, as Bossyut and his team discovered, inactivating Atoh1 in mice triggers the onset of colon cancer.

    Intervallic cell

  • Our genetic evidence from Drosophila and previous in vitro studies of mammalian Atonal homolog 1 (Atoh1, also called Math1 or Hath1) suggest an anti-oncogenic function for the Atonal group of proneural basic helix-loop-helix transcription factors.

  • In the summer of 1984, a team of researchers, collaborating with Weinberg, discovered the human homolog of the neu gene.

    The Emperor of All Maladies

  • * Ullrich actually found the human homolog of the mouse neu gene.

  • "It is not true that this paper: 'An ancient evolutionary origin of the Rag1/2 gene locus' shows a RAG1-RAG2 homolog serving a non-immune system function in sea urchins."

  • The current Whigocratic front-runner, Cleopatra Esposito, has the MMHH (meiotic mr hyde homolog), the so-called "tantrum" gene, on one of her X chromosomes.

  • His argument has always rested on the pillar of homology, yet he doesn't consider two unique and indispensible proteins that have no homolog (even by his relaxed standard) to require a conceptual leap.

  • Jackson and Plano (2000) report that the Yersinia pestis FliH homolog YscL (corresponding to SctL/HrpE in Figure 4a) has low but significant sequence similarity with the e subunit of the archaeal ATPase of Methanococcus jannaschii and the e subunit of the vacuolar ATPase of Desulfurococcus spp.; these subunits are the homologs of the b subunit of the F1F0-ATP synthetase.

  • Mut-7 of C. elegans, required for transposon silencing and RNA interference, is a homolog of Werner syndrome helicase and RNase D. Cell 99, 133-141.
