Dublecortin-like domain 1 found in neuronal migration protein doublecortin (DCX); DCX, also termed doublin or lissencephalin-X (Lis-XDCX), is a microtubule-associated protein (MAP). It belongs to the doublecortin (DCX) family, has double tandem DCX repeats, and is expressed in migrating neurons. Structure studies show that the N-terminal DCX domain has a stable ubiquitin-like fold. DCX is not only a unique MAP in terms of structure, it also interacts with multiple additional proteins. Mutations in the human DCX genes are associated with abnormal neuronal migration, epilepsy, and mental retardation.

N-terminal domain of Kruppel-like factor (KLF) 8, KLF12, and similar proteins; Kruppel-like transcription factors (also known as Krueppel-like transcription factors, KLFs) belong to a family of proteins called the Specificity Protein (SP)/KLF family, characterized by a C-terminal DNA-binding domain of 81 amino acids consisting of three Kruppel-like C2H2 zinc fingers. These factors bind to a loose consensus motif, namely NNRCRCCYY (where N is any nucleotide; R is A/G, and Y is C/T), such as the recurring motifs in GC and GT boxes (5'-GGGGCGGGG-3' and 5-GGTGTGGGG-3') that are present in promoters and more distal regulatory elements of mammalian genes. Although these factors bind to similar elements in vitro, they have distinct activities in vivo depending on their expression profile and the sequence of the N-terminal activation/repression domain, which differ between members. This model represents the related N-terminal activation/repression domains of KLF8 and KLF12.

Dublecortin-like domain 1; Members of the doublecortin (DCX) gene family are microtubule-associated proteins (MAPs). Microtubules are key components of cytoskeleton that are involved in cell movement, shape determination, division and transport. The DCX gene family consists of eleven paralogs in human and mouse, and its protein domains can occur in double tandem or single repeats. The family represents the first repeat of the DCX domain which has a stable ubiquitin-like tertiary fold. Proteins with DCX double tandem domains in general have roles in microtubule (MT) regulation and signal transduction such as X-linked doublecortin (DCX), retinitis pigmentosa-1 (RP1) and doublecortin-like kinase (DCLK).

Dublecortin-like domain 2 found in doublecortin-like kinase 1 (DCLK1); DCLK1 is a member of doublecortin (DCX) protein family that functions as a microtubule-associated protein (MAP), and contains two conserved tubulin binding domains. The DCX domain has a stable ubiquitin-like tertiary fold. Ubiquitin (Ub) is a protein modifier in eukaryotes that is involved in various cellular processes including transcriptional regulation, cell cycle control, and DNA repair. In addition to microtubule binding domains, DCLK encodes a serine/threonine kinase-domain that is similar to Ca/calmodulin-dependent (Cam) protein kinases. DCLK1 appears to regulate cyclic AMP signaling and is involved in neuronal migration, retrograde transport, neuronal apoptosis and neurogenesis. Unlike DCX, the DCLK has varying levels of expression throughout embryonic and adult life.

Doublecortin-like domain 2 found in doublecortin domain-containing protein 2 (DCDC2); DCDC2 is a member of the doublecortin (DCX) family. It is a microtubule-associated protein (MAP) with a stable ubiquitin-like tertiary fold. Ubiquitin (Ub) is a protein modifier in eukaryotes that is involved in various cellular processes, including transcriptional regulation, cell cycle control, and DNA repair. Microtubules are key components of cytoskeleton that are involved in cell movement, shape determination, division and transport. DCDC2 genetic variation in humans is associated with reading disability, attention deficit hyperactivity disorder (ADHD), and difficulties in mathematics. A genetic variant of DCDC2 associates with dyslexia, a common neurobehavioral disorder of reading. DCDC2 protein interacts with many of the same cytoskeleton related proteins that other members of the DCX family interact with.

Doublecortin-like domain found in doublecortin domain-containing protein 5 (DCDC5) and similar proteins; DCDC5 is a member of doublecortin (DCX) family. It is a microtubule-associated protein (MAP) with stable double tandem DCX repeats of ubiquitin-like tertiary fold. Ubiquitin (Ub) is a protein modifier in eukaryotes that is involved in various cellular processes, including transcriptional regulation, cell cycle control, and DNA repair. Microtubules are key components of the cytoskeleton that are involved in cell movement, shape determination, division and transport. DCDC5 is expressed during mitosis and involved in coordinating late cytokinesis. DCDC5 interacts with cytoplasmic dynein and Rab8 as well as with the Rab8 nucleotide exchange factor Rabin8. This family also includes DCDC1, which is a hydrophilic intracellular protein that contains only one DCX repeat. Therefore, DCDC1 might only bind to microtubules without microtubule polymerization properties. DCDC1 is mainly expressed in adult testis.

N-terminal domain of Kruppel-like factor (KLF) 8, KLF12, and similar proteins; Kruppel-like transcription factors (also known as Krueppel-like transcription factors, KLFs) belong to a family of proteins called the Specificity Protein (SP)/KLF family, characterized by a C-terminal DNA-binding domain of 81 amino acids consisting of three Kruppel-like C2H2 zinc fingers. These factors bind to a loose consensus motif, namely NNRCRCCYY (where N is any nucleotide; R is A/G, and Y is C/T), such as the recurring motifs in GC and GT boxes (5'-GGGGCGGGG-3' and 5-GGTGTGGGG-3') that are present in promoters and more distal regulatory elements of mammalian genes. Although these factors bind to similar elements in vitro, they have distinct activities in vivo depending on their expression profile and the sequence of the N-terminal activation/repression domain, which differ between members. This model represents the related N-terminal activation/repression domains of KLF8 and KLF12.
