肾母细胞瘤蛋白重组兔单抗

WT1

Wilms tumor protein

Homodimer. Interacts with WTIP. Interacts with actively translating polysomes. Detected in nuclear ribonucleoprotein (mRNP) particles. Interacts with HNRNPU via the zinc-finger region. Interacts with U2AF2. Interacts with CITED2. Interacts with ZNF224 via the zinc-finger region. Interacts with WTAP and SRY. Interacts with FAM123B/WTX. Interacts with RBM4.

Nucleus. Nucleus, nucleolus. Cytoplasm. Note=Shuttles between nucleus and cytoplasm.
Isoform 1: Nucleus speckle.
Isoform 4: Nucleus, nucleoplasm.

Expressed in the kidney and a subset of hematopoietic cells.

Defects in WT1 are the cause of Frasier syndrome (FS) [MIM:136680]. FS is characterized by a slowly progressing nephropathy leading to renal failure in adolescence or early adulthood, male pseudohermaphroditism, and no Wilms tumor. As for histological findings of the kidneys, focal glomerular sclerosis is often observed. There is phenotypic overlap with Denys-Drash syndrome. Inheritance is autosomal dominant.
Defects in WT1 are the cause of Wilms tumor 1 (WT1) [MIM:194070]. WT is an embryonal malignancy of the kidney that affects approximately 1 in 10'000 infants and young children. It occurs both in sporadic and hereditary forms.
Defects in WT1 are the cause of Denys-Drash syndrome (DDS) [MIM:194080]. DDS is a typical nephropathy characterized by diffuse mesangial sclerosis, genital abnormalities, and/or Wilms tumor. There is phenotypic overlap with WAGR syndrome and Frasier syndrome. Inheritance is autosomal dominant, but most cases are sporadic.

Belongs to the EGR C2H2-type zinc-finger protein family.
Contains 4 C2H2-type zinc fingers.

Transcription factor that plays an important role in cellular development and cell survival. Regulates the expression of numerous target genes, including EPO. Plays an essential role for development of the urogenital system. Recognizes and binds to the DNA sequence 5'-CGCCCCCGC-3'. It has a tumor suppressor as well as an oncogenic role in tumor formation. Function may be isoform-specific: isoforms lacking the KTS motif may act as transcription factors. Isoforms containing the KTS motif may bind mRNA and play a role in mRNA metabolism or splicing. Isoform 1 has lower affinity for DNA, and can bind RNA.
