Prothymosin α (ProTα) is a 12.5 kDa acidic polypeptide that is considered to have a nuclear function related to cell proliferation. Inspection of its amino acid sequence revealed the presence of sequences that may serve as targets for phosphorylation by casein kinase‐2 (CK‐2). ProTα isolated from calf thymocytes was phosphorylated in vitro by CK‐2. The phosphorylation sites are Ser and Thr residues located among the first 14 amino acid residues in the ProTα sequence. Another site that is… Expand
A 180-kDa Protein Kinase Seems to Be Responsible for the Phosphorylation of Prothymosin α Observed in Proliferating Cells*
TLDR
The isolation and characterization of a ProT α-phosphorylating kinase (ProTαK) from mouse splenocytes is reported that seems to be responsible for the in vivo phosphorylation of ProTα and that differs from other protein kinases reported to date. Expand
Phosphorylation of Prothymosin α. An Approach to Its Biological Significance.
TLDR
Phosphorylation of ProTα seems to be related to its antiapoptotic activity, although other possibilities cannot be discarded. Expand
Properties of the protein kinase that phosphorylates prothymosin α
TLDR
ProTαK is an apparently novel enzyme that is responsible for the phosphorylation of prothymosin α, involved in the proliferation of mammalian cells, and its principal substrate in proliferating cells appears to be ProTa. Expand
The M2-type isoenzyme of pyruvate kinase phosphorylates prothymosin α in proliferating lymphocytes.
TLDR
Mass spectrometric analysis of ProTαK purified from human tumor lymphocytes (NC37 cells) enabled us to identify this enzyme as the M2-type isoenzyme of pyruvate kinase, the activity of which is dependent on phosphorylation. Expand
Prothymosin α in Vivo Contains Phosphorylated Glutamic Acid Residues*
TLDR
The data demonstrate that prothymosin α is energy-rich by virtue of stoichiometric amounts of glutamyl phosphate, based on the observation that greater than 90% of the phosphate initially found at pH 7 disappeared at the extremes of pH. Expand
Does Prothymosin α Affect the Phosphorylation of Elongation Factor 2?*
TLDR
The data do not support a direct relationship between the function of prothymosin α and the phosphorylation of eEF-2, and any procedure that decreases the effective fluoride concentration will relieve the inhibition and appear to activate. Expand
Metabolic regulation of protein‐bound glutamyl phosphates: Insights into the function of prothymosin α
TLDR
The data suggest that prothymosin α fuels an energy‐requiring step in the production, processing, or export of RNA. Expand
Turnover of the Acyl Phosphates of Human and Murine Prothymosin α in Vivo *
TLDR
The data suggest that the “activity” of prothymosin α involves the turnover of its acyl phosphates and that it participates in a function common to all nucleated mammalian cells regardless of whether they are quiescent or undergoing rapid proliferation. Expand
Prothymosin alpha binds histones in vitro and shows activity in nucleosome assembly assay.
TLDR
Experiments show that calf Pro Talpha selectively binds to core histones and histone H1 in vitro, and the possibility that Pro T alpha plays a role in chromatin remodelling is discussed. Expand
Prothymosin α Functions as a Cellular Oncoprotein by Inducing Transformation of Rodent Fibroblasts in Vitro *
TLDR
The results demonstrate that the ProTα gene may function as an oncogene when stably expressed in Rat-1 cells and may be an important downstream cellular target for inducers of cellular transformation, which may include Epstein-Barr virus and c-myc. Expand

Nuclear targeting of prothymosin alpha.
TLDR
The basic cluster of amino acids at the carboxyl terminus of prothymosin alpha, TKKQKT, has been identified as part of the nuclear targeting signal, whereas the basic clusterof amino acids situated within the thymos in alpha 1 sequence at the amino terminus failed to effect nuclear transport.

Detection and quantification of phosphotyrosine in proteins.
TLDR
This chapter discusses the detection and quantification of phosphotyrosine in proteins, and describes the kinases associated with the cell surface receptors for two polypeptide growth factors, epidermal growth factor and platelet-derived growth factor, and with the transforming proteins of at least five genetically distinct groups of retroviruses.

The phosphorylation of nucleoplasmin by casein kinase‐2 is resistant to heparin inhibition
TLDR
Findings indicate that the phosphorylation of nucleoplasmin by purified casein kinase‐2, while showing typical response to DRB and spermine, exhibits anomalous behavior in its resistance to heparin inhibition. Expand
Isolation and partial sequencing of the human prothymosin alpha gene family. Evidence against export of the gene products.
TLDR
The localization of prothymosin alpha mRNAs on free polysomes, together with the partial nucleotide sequences of the genes, strongly suggest an intracellular function for prothyon alpha and the possibility must be raised that the protein and its peptide derivatives act as xenobiotics when introduced into assays of immune function. Expand
Expression of the rat prothymosin alpha gene during T-lymphocyte proliferation and liver regeneration.
TLDR
It is suggested that ProT alpha is required throughout all the stages of the cell cycle, resembling a constitutively expressed gene rather than one strictly involved in cell proliferation. Expand
Synthesis and apparent secretion of prothymosin alpha by different subpopulations of calf and rat thymocytes.
TLDR
All the calf and rat thymocytes subpopulations show a similar capacity to secrete ProT alpha, the amount of the newly synthesized polypeptide recovered from cell culture supernatants being 80-90% of that found in thymocyte extracts. Expand

Proteolytic digestion with Staphylococcus aureus V8 protease of 32P-labelled P1 both in vivo and in vitro revealed that casein kinase-2 may be one of the kinases responsible for the phosphorylation in vivo. Expand
