Mouse Anti-USP9X Recombinant Antibody (2A9) (CBMAB-U0046-CQ)

Ubiquitin Specific Peptidase 9, X-Linked

USP9X is a member of the peptidase C19 family and is similar to ubiquitin-specific proteases. Mutations in USP9X have been associated with Turner syndrome.

Deubiquitinase involved both in the processing of ubiquitin precursors and of ubiquitinated proteins (PubMed:19135894, PubMed:25944111, PubMed:18254724, PubMed:22371489, PubMed:29626158).
May therefore play an important regulatory role at the level of protein turnover by preventing degradation of proteins through the removal of conjugated ubiquitin (PubMed:19135894, PubMed:25944111, PubMed:22371489, PubMed:18254724, PubMed:29626158).
Specifically hydrolyzes 'Lys-63'-, 'Lys-48'-, 'Lys-29'- and 'Lys-33'-linked polyubiquitins chains (PubMed:25944111, PubMed:18254724, PubMed:33378666).
Essential component of TGF-beta/BMP signaling cascade (PubMed:19135894).
Specifically deubiquitinates monoubiquitinated SMAD4, opposing the activity of E3 ubiquitin-protein ligase TRIM33 (PubMed:19135894).
Deubiquitinates alkylation repair enzyme ALKBH3 (PubMed:25944111).
OTUD4 recruits USP7 and USP9X to stabilize ALKBH3, thereby promoting the repair of alkylated DNA lesions (PubMed:25944111).
Deubiquitinates mTORC2 complex component RICTOR at 'Lys-294' by removing 'Lys-63'-linked polyubiquitin chains, stabilizing RICTOR and enhancing its binding to MTOR, thus promoting mTORC2 complex assembly (PubMed:33378666).
Regulates chromosome alignment and segregation in mitosis by regulating the localization of BIRC5/survivin to mitotic centromeres (PubMed:16322459).
Involved in axonal growth and neuronal cell migration (PubMed:24607389).
Regulates cellular clock function by enhancing the protein stability and transcriptional activity of the core circadian protein BMAL1 via its deubiquitinating activity (PubMed:29626158).
Acts as a regulator of peroxisome import by mediating deubiquitination of PEX5: specifically deubiquitinates PEX5 monoubiquitinated at 'Cys-11' following its retrotranslocation into the cytosol, resetting PEX5 for a subsequent import cycle (PubMed:22371489).
Deubiquitinates PEG10 (By similarity).

Intellectual developmental disorder, X-linked 99 (XLID99):
A disorder characterized by significantly below average general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period. Intellectual deficiency is the only primary symptom of non-syndromic X-linked forms, while syndromic forms present with associated physical, neurological and/or psychiatric manifestations.
Intellectual developmental disorder, X-linked 99, syndromic, female-restricted (MRXS99F):
A form of intellectual disability, a disorder characterized by significantly below average general intellectual functioning, associated with impairments in adaptive behavior and manifested during the developmental period. MRXS99F affected females manifest intellectual disability, developmental delay, facial dysmorphism, short stature, and distinct congenital malformations comprising choanal atresia, anal abnormalities, post-axial polydactyly, heart defects, hypomastia, cleft palate/bifid uvula, progressive scoliosis, and structural brain abnormalities. Inheritance is X-linked dominant.
