Insights

Nucleoside diphosphate kinases (Nm23/NDPKs) regulate cellular functions. This review explores the subcellular localization of Nm23-H1/NDPK A and Nm23-H2/NDPK B to understand their roles in normal and cancer cells.

Area of Science:

  • Molecular Biology
  • Cell Biology
  • Biochemistry

Background:

  • Nm23/NDPK proteins are involved in critical cellular processes like proliferation, differentiation, and apoptosis.
  • Research has primarily focused on the role of Nm23/NDPKs in tumor metastasis.
  • The specific functions of individual Nm23/NDPK family members remain largely unclear.

Purpose of the Study:

  • To review recent findings on the subcellular localization of Nm23-H1/NDPK A and Nm23-H2/NDPK B.
  • To correlate subcellular localization with the diverse biological functions of these proteins.
  • To elucidate the roles of Nm23-H1 and Nm23-H2 in both normal and malignant cells.

Main Methods:

  • Literature review of experimental data.
  • Analysis of studies investigating subcellular localization.
  • Integration of findings on localization and function.

Main Results:

  • Nm23-H1/NDPK A exhibits specific subcellular localizations.
  • Nm23-H2/NDPK B also demonstrates distinct subcellular distributions.
  • Localization patterns provide insights into differential protein functions.

Conclusions:

  • Subcellular localization is a key determinant of Nm23-H1/NDPK A and Nm23-H2/NDPK B functions.
  • Understanding localization aids in deciphering their roles in cellular processes and disease.
  • Further research into Nm23/NDPK localization is crucial for understanding normal physiology and cancer progression.

Nuclear Localization Signals and Import01:46

Nuclear Localization Signals and Import

Proteins targeted to the nucleus carry short stretches of amino acid sequences called the nuclear localization signal or NLS. Classical nuclear localization signals are of two types: monopartite and bipartite NLS. Monopartite classical NLS (cNLS) consists of a single cluster of 4-8 amino acids. Bipartite cNLS consists of two clusters of  2-3 amino acids and a 9-12 residue long proline-rich linker bridging the two clusters. Signal clusters are rich in positively charged amino acids such as...
Nuclear Protein Sorting01:34

Nuclear Protein Sorting

Nuclear protein sorting is the selective trafficking of histones, polymerases, gene regulatory proteins into the nucleus and exporting RNAs and ribosomes to the cytosol. It is a tightly controlled process that regulates gene expression within a cell.
Proteins targeted to the nucleus carry nuclear localization signals or NLS recognized by import receptors in the cytosol. Similarly, proteins with nuclear export signals are recognized by export receptors. Import and export receptors are...
Regulation of Nuclear Protein Sorting01:45

Regulation of Nuclear Protein Sorting

Nuclear protein sorting regulates nucleus composition and gene expression, crucial for determining the fate of a eukaryotic cell. Hence, the entry and exit of molecules across the nuclear envelope is a tightly controlled process. Nuclear protein sorting can be inhibited by one of the following ways: 1) masking cargo signal sequences, 2) modifying the nuclear receptor's affinity for cargo, 3) controlling the nuclear pore size, 4) retaining the cargo during its transit to the cytosol or the...
Regulated mRNA Transport02:22

Regulated mRNA Transport

In eukaryotes, transcription and translation are compartmentalized; an mRNA is first synthesized in the nucleus and then selectively transported to the cytoplasm for protein synthesis. Before transport, a pre-mRNA undergoes several steps of post-transcriptional modifications including splicing, 5' capping, and the addition of a poly-adenine tail. Various proteins bind to the pre-mRNA during these modifications. The mRNA transport takes place with the help of multiple proteins playing specific...
Nuclear Export01:42

Nuclear Export

The nucleus restricts several proteins within and allows others to pass. The restricted proteins possess a nuclear retention sequence or NRS, anchoring them to the nuclear lamins and preventing their transport to the cytosol. The non-restricted proteins, after their synthesis, are transported to their site of action, such as the cytosol or other organelles, with the help of nuclear export signals or NES.
NES are of three types- the canonical 10-residue long leucine-rich signal and other...
The Nucleolus02:55

The Nucleolus

The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...
