- [Expressed only in G0 by human RBL2 Gene (RB Family), 1139-aa 128-kDa nuclear Retinoblastoma-Like 2 protein binds to adenovirus E1A protein and to cyclins A and E, associates preferentially with E2F5, inhibits E2F-mediated trans-activation, and may function in cell cycle regulation. Ser-672 phosphorylation in G1 leads to ubiquitin-dependent proteolysis of RBL2. (NCI) ( NCI )] (UMLS (NCI) C0249759) =Amino Acid, Peptide, or Protein; Biologically Active Substance ;

- [Ubiquitously expressed (highest in testis and brain) human TBPL1 Gene (TBP Family), encodes 186-aa 21-kDa DNA-binding TBP-Like Protein 1, which serves the same function as TBP, substituting for TBP at some promoters not recognized by TFIID. TBPL1 binds TFIIA and TFIIB, does not bind the TATA box, may be important in expression of some developmentally regulated genes, and is essential for spermiogenesis.

- 3. 28 kDa Heat Shock Protein
- [Heat-shock proteins belong to a large group stress proteins, induced in response to environmental challenges and developmental transitions. Involved in stress resistance and actin organization, synthesis of HSP27 is correlated with the acquisition of thermotolerance. HSP27 belongs to the HSP20 family and shows sequence similarity to alpha-crystallins. Cytoplasmic HSP27 associates with alpha- and beta-tubulin, and with interphase and mitotic microtubules. HSP27 translocates to the nucleus during heat shock and is phosphorylated on exposure to PKC activators and heat shock.

RPS6KA5 activity requires the presence of both kinase domains. Likely activated by ERK1/2 and p38 Ser/Thr phosphorylations, RPS6KA5 transiently dissociates from complexes with ERK1/2 following mitogenic stimulation and may mediate growth factor and stress induced activation of transcription factor CREB. RPS6KA5 also associates with MAPK14/p38alpha. (NCI) ( NCI )] (UMLS (NCI) C0913240) Mitogen- and Stress-Activated Protein Kinase 1;

- 4. 33kDa Phototransducing Protein
- [Phosducin, encoded by the PDC gene, is a phosphoprotein that is located in the outer and inner segments of the rod cells in the retina. This protein may participate in the regulation of visual phototransduction or in the integration of photoreceptor metabolism. It modulates the phototransduction cascade by interacting with the beta and gamma subunits of the retinal G-protein transducin. This gene is a potential candidate gene for retinitis pigmentosa and Usher syndrome type II. Alternatively spliced transcript variants encoding different isoforms have been identified.

| - 9. 95 kDa Melanocyte-Specific Secreted Glycoprotein
- [Expressed in melanocytes and melanomas by human SILV Gene (PMEL17/NMB Family), 661-aa 70-kDa (precursor) Melanocyte Lineage-Specific Antigen gp100is a probable type I membrane protein containing a putative leader sequence, a potential membrane anchor segment, 5 potential N-glycosylation sites, high levels of serine and threonine, a PKD domain, and amino acid similarity to tyrosinase and CAS2 protein. PMEL17 cross reacts with antityrosinase antibodies and expression correlates with melanin content. The soluble ME20-S form is a probable proteolytic cleavage product. CD8 T lymphocytes recognize a noncontiguous spliced nonameric sequence of gp100 on melanoma cells. Splicing appears to occur by transpeptidation involving an acyl-enzyme intermediate.

- 5. 350/400 kDa PCAF-Associated Factor
- [Encoded by human TRRAP Gene (TRA1 Kinase Family), 3859-aa 438-kDa and 3830-aa isoforms of adapter protein Transformation/Transcription Domain-Associated Protein, containing 2 TPR repeats, are a component of multiprotein chromatin PCAF histone acetylase complex, TFTC-HAT complex, STAGA complex, and TIP60 HAT and BAF53 complexes, which acetylate histone H4/H2A in nucleosomes. Required for p53-, E2F1- and E2F4-mediated transcription activation, TRRAP interacts with GCN5L2, TP53, MYC, E2F1, and E2F4 transcription factors; it probably links E1A, MYC, and E2F1 to HAT complexes allowing transcription activation. Lacking kinase catalytic motifs and activity, the PI3K/PI4K domain is required for recruitment of HAT complexes and MYC-dependent transactivation. Cell cycle TRRAP is probably not required in transcription activation following histone acetylation. (NCI) ( NCI )] (UMLS (NCI) C1336800) PAF350/400;
