Karyopherin alpha 1

NPI-1, Importin alpha, importin alpha5, NPII, KPNA1
Recombination activating proteins RAG1 and RAG2 regulate and mediate V(D)J recombination, the process by which genes for immunoglobulins and T-cell receptors are generated. Several other ubiquitously expressed proteins are thought to be recruited in the recombination process. Among these are the genes affected in severe combined immune deficiency and genes involved in ds-DNA break repair. The protein encoded by this gene interacts with RAG1 and may play a role in V(D)J recombination. Two transcript variants, one protein-coding and the other not, have been found for this gene.

Mergen et al., Antalya, Turkey. In Pituitary, Dec 2015
BACKGROUND: Familial central diabetes insipidus (DI), usually an autosomal dominant disorder, is caused by mutations in arginine vasopressin-neurophysin II (AVP-NPII) gene that leads to aberrant preprohormone processing and gradual destruction of AVP-secreting cells.

Skordis et al., Cyprus. In Hormones (athens), Jul 2015
The disorder is caused by mutations affecting the AVP-NPII gene, resulting in absent or deficient secretion of the antidiuretic hormone arginine vasopressin (AVP) by the neurohypophysis.
Early-onset central diabetes insipidus is associated with de novo arginine vasopressin-neurophysin II or Wolfram syndrome 1 gene mutations.
Maghnie et al., Napoli, Italy. In Eur J Endocrinol, Apr 2015
OBJECTIVE: Idiopathic early-onset central diabetes insipidus (CDI) might be due to mutations of arginine vasopressin-neurophysin II (AVP-NPII (AVP)) or wolframin (WFS1) genes.
Autosomal dominant familial neurohypophyseal diabetes insipidus caused by a mutation in the arginine-vasopressin II gene in four generations of a Korean family.
Yoo et al., Pusan, South Korea. In Ann Pediatr Endocrinol Metab, 2014
Autosomal dominant neurohypophyseal diabetes insipidus is a rare form of central diabetes insipidus that is caused by mutations in the vasopressin-neurophysin II (AVP-NPII) gene.
BIG3 Inhibits the Estrogen-Dependent Nuclear Translocation of PHB2 via Multiple Karyopherin-Alpha Proteins in Breast Cancer Cells.
Katagiri et al., Tokushima, Japan. In Plos One, 2014
We found that overexpressed PHB2 interacted with KPNA1, KPNA5, and KPNA6, thereby leading to the E2-dependent translocation of PHB2 into the nuclei of breast cancer cells.
