Protein

Serine/threonine-protein kinase Nek9

Gene

NEK9

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Pleiotropic regulator of mitotic progression, participating in the control of spindle dynamics and chromosome separation. Phosphorylates different histones, myelin basic protein, beta-casein, and BICD2. Phosphorylates histone H3 on serine and threonine residues and beta-casein on serine residues. Important for G1/S transition and S phase progression. Phosphorylates NEK6 and NEK7 and stimulates their activity by releasing the autoinhibitory functions of Tyr-108 and Tyr-97 respectively.3 Publications

Catalytic activityi

ATP + a protein = ADP + a phosphoprotein.

Cofactori

Mg2+

Enzyme regulationi

Activated during mitosis by intramolecular autophosphorylation. Activity and autophosphorylation is activated by manganese >> magnesium ions. Sensitive to increasing concentration of detergents. It is not cell-cycle regulated but activity is higher in G0-arrested cells.

Involvement in diseasei

Lethal congenital contracture syndrome 10 (LCCS10)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA form of lethal congenital contracture syndrome, an autosomal recessive disorder characterized by degeneration of anterior horn neurons, extreme skeletal muscle atrophy and congenital non-progressive joint contractures. The contractures can involve the upper or lower limbs and/or the vertebral column, leading to various degrees of flexion or extension limitations evident at birth.
See also OMIM:617022
Nevus comedonicus (NC)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA rare type of epidermal nevus characterized by closely arranged, dilated, plugged follicular ostia in a honeycomb pattern. The plugged ostia contain lamellated keratinaceous material, and their appearance resembles black dots. NC may be non-pyogenic with an acne-like appearance or associated with the formation of cysts, papules, pustules, and abscesses. Most commonly it affects the face and neck area and, by exception, other anatomical regions, including genital area, palms, and soles. NC lesions might present with various patterns of distribution: unilateral, bilateral, linear, interrupted, segmental, or blaschkoid.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
