Disease relevance of LanB1

  • These results suggest that DGNBP-1 functions as a pattern recognition receptor for LPS from Gram-negative bacteria and beta-1, 3-glucan from fungi and plays an important role in non-self recognition and the subsequent immune signal transmission for the induction of antimicrobial peptide genes in the Drosophila innate immune system [1].
  • Interaction of Bombyx mori nucleopolyhedrovirus BRO-A and host cell protein laminin [2].
  • Generalized epilepsy with febrile seizures plus type 1 is an inherited human epileptic syndrome, associated with a cysteine-to-tryptophan (C121W) mutation in the extracellular immunoglobin domain of the auxiliary beta1 subunit of the voltage-gated sodium channel [3].

Associations of LanB1 with chemical compounds

  • alpha-, beta- or gamma-chain-specific RNA interference of laminin assembly in Drosophila Kc167 cells [10].
  • Further, we show that neurotic is required for Fringe activity, which encodes a fucose-specific beta1, 3 N-acetylglucosaminyltransferase, previously shown to modulate Notch receptor activity [17].
  • We hypothesized that a tyrosine residue in the cytoplasmic domain of beta 1 may be important for ankyrin recruitment and tested our hypothesis using beta 1 mutants replacing Tyr(181) with alanine (beta 1Y181A), phenylalanine (beta 1Y181F), or glutamate (beta 1Y181E), or a truncated construct deleting all residues beyond Tyr(181) (beta 1L182(STOP)) [18].
  • 6. Etomidate acting at beta1 (S290)-containing mammalian GABA(A) receptors is known to produce only a modest GABA-modulatory effect [19].
  • Two-dimensional gel electrophoresis separated at least 28 proteins, 13 of which were identified with monospecific antibodies to alpha6/C2 (five species), alpha2/C3 (three species), alpha7/C8 (three species), alpha5/zeta, and beta1/Y subunits [20].
