  • fold
  • The bundle defines a previously unobserved fold comprising a two-helix hairpin motif repeated three times around the central axis of the channel, without the inverted repeat of mammalian-type urea transporters. (nih.gov)
  • thus
  • We now find that a cluster of acidic residues including two serines phosphorylated by casein kinase 2 is required for the localization of VMAT2 to LDCVs.The motif thus acts as a signal for retention on LDCVs.Phosphorylation of the acidic cluster thus appears to reduce the localization of VMAT2 to LDCVs by inactivating a retention mechanism.

  • The motif thus acts as a signal for retention on LDCVs. (nih.gov)
  • among
  • SALL4 has at least one canonical nuclear localization signal (NLS) with the K-K/R-X-K/R motif in the N-terminal portion of the protein shared among both A and B isoforms (residues 64-67). (wikipedia.org)
