The common N-terminus exon of GMCβ4 encodes the highly conserved beta-alpha-beta fold of the ADP-binding domain common to all GMC oxidoreductases.
Each chain of ValA encompasses the expected N-terminal NAD+-binding domain and C-terminal metal-binding domain common to the DHQS-like superfamily.
In this study, we analysed phosphoinositide production in two cell lines with ablated PI3Ks: cells lacking all five type I PI3Ks and PTEN activity (Hoeller and Kay, 2007) and cells lacking the five type I kinases and an additional unique related kinase lacking the Ras-binding domain common to this family of enzymes (Hoeller and Kay, 2007) (Fig. 3).
Alignment of predicted C1, C1-I, FaMYB1, AtMYB90/PG-1 aNtAN2AN2 protein sequences indicates that sequence similarity is primarily limited to the highly conserved R2R3 DNA-binding domains common to this family of plant myb genes (Fig. 5).
The hyaluronan binding domain, common in all four lecticans [ 36], is especially important during inflammatory process and tumor metastasis [ 37], while the CLDs are currently involved in processes like cell-cell adhesion [ 38] and immune response to pathogens [ 39– 41].
The β-chain contains the polyanionic binding site for the cationic laminin globular domain common to several matrix proteins, such as agrin, perlecan, proteoglycans, and laminin itself [ 99, 100].
While PKCθ also contains the lipid binding C1A and C1B domains common to other PKC isoforms, a model was proposed whereby the C2-domain of PKCθ binds the lipid-rich plasma membrane and unleashes the protein from a folded state, leading to a fully active enzyme [ 7].
Soon after the gene's discovery, two groups generated p63 knockout models but used different embryonic stem cell ablation technologies for p63 exon disruption 2, 3. McKeon and colleagues replaced Exons 6-8 in the DNA binding domain (which is common to both TA and ΔN isoforms) with a Neo cassette, leading to a complete loss of all p63 proteins.
Mutations of the common prolyl hydroxylation and pVHL binding domain lead to the loss of CA9 mRNA, and protein [ 19].
OSBPL, Oxysterol-binding proteins are a large family involved in diverse cellular processes with an oxysterol binding domain as common feature [ 66, 67] and we have studied one subfamily with the human members located on chromosomes 2, 7 and 17 (Fig. 6).
