    text with MTDH, colocalize to nuclear bodies containing histone deacetylases, which are known to promote ZBTB16-mediated repression
    basic FUNCTION
  • recruiting nuclear histone deacetylase through nuclear corepressor N-COR
  • co-expression of ZBTB16 and RB1 results in enhancement of transcriptional repression of ZBTB16 and E2F/Rb target genes, indicating functional co-operation between the two proteins
  • DNA sequence-specific transcriptional repressor
  • playing a key role in human myeloid development
  • regulator of HOX gene expression and of myeloid maturation
  • spermatogonia-specific transcription factor in the testis that is required to regulate self-renewal and maintenance of the stem cell pool
  • playing a significant stimulatory role in megakaryocytic development, seemingly mediated in part by induction of TpoR expression at transcriptional level
  • activates CXCR4 translation in megakaryopoiesis
  • may be involved in a general mechanism in the regulation of hematopoiesis, linking lineage-specific transcription factors, miRNAs and key mRNA targets, particularly growth factor/chemokine receptors
  • also required for stem-cell self-renewal and maintenance in adult male germ cells
  • invariant natural killer T cells -specific transcription factor that is necessary for full functionality (
  • during homeostasis, restricts proliferation and differentiation of cord blood-derived myeloid progenitors to maintain a balance between the progenitor and mature cell compartments
  • may play a role in differentiation of hematopoietic progenitors
  • regulates the expression of genes involved in cell growth and apoptosis including c-myc
  • sufficient to promote T cell effector functions and ZBTB16 acts independently of SAP- and Fyn-mediated signaling pathways
  • opposes MTOR activity and define a cellular signaling network controlling spermatogonial progenitor cells (SPC) homeostasis whereby MTOR integrates mitogenic signals received by SPCs and determines their sensitivity to self-renewal stimuli
  • role for ZBTB16-mediated DDIT4 expression in inhibiting MTOR activation in spermatogonial progenitor cells
  • is remarkable in that it is a transcription factor capable of inducing an effector program in the absence of T cell agonist interactions or cell division
  • transports CUL3 to the nucleus, where the two proteins are associated within a chromatin-modifying complex
  • regulates the expression of a surprisingly small set of genes, many with known immune functions, and of a limited number of genes essential for NKT cell function
  • implicated as a novel determinant of substrate utilization in brown adipocytes and of adiposity

    protein
  • GATA2 modifying transactivation capacity
  • interacting with GATA1, activating thrombopoietin receptor and inducing megakaryocyte development
  • interacting with CRMP1 and GNE
  • upstream regulator of Runx2/CBFA1
  • interacting with ZBTB32 (ZBTB16 differentially participate in the regulation of osteoblastic differentiation via the BMP2 and CBFA1 signaling pathways, respectively)
  • ZBTB16 (PLZF) specifically bound to GNAO1
  • interacts with RB1 (interaction between ZBTB16 and RB1 is mediated through the RB1 pocket and the region of ZBTB16 that lies between its transcriptional repression (poxvirus and zinc-finger, POZ) and DNA-binding (zinc-finger) domains)
  • ZBTB16-mediated control on KIT expression in CD34(+) cells and early erythropoiesis
  • interacting protein of MTDH (interact in mammalian cells via the N- and C termini of MTDH and a region C terminal to the RD2 domain of ZBTB16)
  • interacting with stress-induced cytokines that can act by interfering with the capacity of ZBTB16 to inhibit proliferation and differentiation
  • repressed CEBPA transcription but did not bind to its promoter, indicating indirect regulation
  • transcriptional target for the CUX1 repressor (the novel genetic relationship between CUX1 and PLZF could be of relevance to human diseases, such as leukemia)
  • mechanistically, SALL4 sequesters ZBTB16 to noncognate chromatin domains to induce expression of KIT, a target of ZBTB16-mediated repression required for differentiation
  • prominently associated with CUL3, an E3 ubiquitin ligase previously shown to use BTB domain-containing proteins as adaptors for substrate binding
  • USP37 interacted with ZBTB16/RARA through the ZBTB16 moiety and sustained ZBTB16/RARA steady state levels
  • potential role for SLAMF6 in the induction of ZBTB16
  • RARA-ZBTB16 acts as a modifier oncogene that subverts differentiation in the granulocytic lineage by associating with CEBPA and inhibiting its activity
  • HOXA5, HOXC5, HOXB5 interacts with promyelocytic leukemia zinc finger (ZBTB16) biochemically and genetically to restrict SHH expression

  • Plzf-deficient mice (luxoid, Zbtb16Lu) had severe patterning defects of the limbs and the axial skeleton
  • heterozygous mutant (luxoid.Zbtb16(LU)/J) mice deficient in Zbtb16 have hearing and responses to acoustic trauma similar to their wild type littermates but are unable to generate conditioning-induced protection from acoustic trauma
