9.A.54.1.1









Probable lysosomal cobalamin exporter, NESI or C61F disease protein; defective in cobalamin F type disease (540aas; 9 TMSs in a 5 + 4 arrangement) (Ruivo et al., 2009; Rutsch et al., 2009; Gailus et al., 2010; Wilcken, 2012; Braz et al. 2022) (also called LMBR1 domain-containing protein or LMBRD1; liver regeneration p53-related protein, Lipocalin-interacting membrane receptor, limb region 1 protein, etc.) Homologues are present in all eukaryotes and probably some bacteria (e.g., EcsB protein of Bacillus cereus (gi#47570159; 10 TMSs; distantly related to 3.A.1.128.2). RodA of E. coli (9.B.3.1.2) may also be distantly related.

9.A.54.3.5









G-protein coupled receptor-associated protein, LMBRD2, of 695 aas and 8 TMSs in a 2 + 2 + 4 TMS arrangement. De novo missense variants in LMBRD2 are associated with developmental and motor delays, brain structure abnormalities and dysmorphic features (Malhotra et al. 2021). it is a potential regulator of beta2 adrenoceptor signaling (Paek et al. 2017).
