Abstract: The invention relates to the identification of a highly stable single domain antibody scaffold (hs2dAb) and its use in generating synthetic single domain antibody library (hs2dAb-L1). The invention also relates to antigen-binding proteins comprising said stable single domain antibody scaffold and their uses, in particular as therapeutics.

Abstract: The inventors have identified an autosomal dominant (AD) missense mutation in the RAC2 gene (coding for Ras-related botulinum toxin substrate 2 (RAC2)) in three Severe combined immunodeficiencies (SCID) patients whose clinical presentation overlaps with the RD SCID form but who lack AK2 mutations and deafness. Using biochemical and in vitro differentiation assays, the inventors demonstrated that the RAC2 mutation was closely related to an impairment in cell differentiation capacity and defects in cellular and mitochondrial networks. Taken as a whole, the data demonstrate that a dominant gain-of-function (GOF) mutation in the RAC2 protein's GDP/GTP binding site inhibits HSPC differentiation and leads to a severe AD form of SCID with a clinical presentation of RD. Accordingly, the results prompt to consider that introduction of the identified RAC2 mutein in the hematopoietic lineage would be suitable for inducing full ablation of hematopoiesis.

Abstract: Active forms of specific anti Rho GTPase conformational single domain antibodies are useful in the therapeutic and diagnostic fields. In particular, single domain antibodies wherein the amino acid sequences of CDR1-IMGT, CDR2-IMGT and CDR3-IMGT have at least 90% of identity with the amino acid sequences of the CDR1-IMGT, CDR2-IMGT and CDR3-IMGT of the H12, B6, 4P75, 4SP1, 4SNP36, 4SNP61, 5SP10, 5SP11, 5SP58, 5SNP47, 5SNP48, 5SNP65, B20, B15, B5, B71, E3, A6, G12, NB61, 212B, 111B or 404F (hs2dAb) are defined in Table B.
