Recombinant protein was captured through anti-DDK affinity column followed by conventional chromatography steps. (origene.com)

It has been associated with heterochromatin and PML-NBs (Promyelocytic Leukaemia nuclear bodies) and has been implicated in many nuclear processes including transcription and cell cycle regulation. (wikipedia.org)
Its repression can be relieved by the sequestration of this protein into promyelocytic leukemia nuclear bodies or nucleoli. (wikipedia.org)
The SMN protein is ubiquitously expressed and is present both in the cytoplasm and in the nucleus where it localizes in Cajal bodies. (cnrs.fr)
Membraneless RNP subcompartments found in the nucleus are referred to as nuclear bodies (e.g. (bvsalud.org)

This region contains a glutamine/asparagine (Q/N) prion-like domain that participates in protein-protein interactions and in the TDP-43 aggregation process 4 , 5 . (nature.com)

One of the most highly characterized hypertrophic signaling cascades involves the calcium dependent serine/threonine protein phosphatase calcineurin. (bmj.com)

Chromatin immunoprecipitation (ChiP) assay revealed that Cd substantially increased the ARE occupancy of Nrf2 but not keap1, indicating Keap1 may recycle from the nucleus to the cytoplasm. (cdc.gov)

Transport vesicles then take the modified proteins to the nearby Golgi body, where they are processed further and sorted for transport. (visiblebody.com)
