Clonality | Polyclonal |
Calculated MW | 45 KDa |
Physical State | Liquid |
Immunogen | KLH conjugated synthetic peptide derived from human FEZ1 |
Epitope Specificity | 301-392/392 |
Isotype | IgG |
Purity | affinity purified by Protein A |
Buffer | 0.01M TBS (pH7.4) with 1% BSA, 0.02% Proclin300 and 50% Glycerol. |
SUBCELLULAR LOCATION | Cytoplasm, cytoskeleton, centrosome. Cellmembrane (By similarity). Note=Co-localizes with both, alpha- andgamma-tubulin. Translocated from the plasma membrane to thecytoplasm by activation of the PKC zeta (By similarity). |
SIMILARITY | Belongs to the zygin family. |
SUBUNIT | Homodimer; difulfide-linked. May form heterodimers withFEZ2. Interacts with the NH2-terminal variable region (V1) of PKCzeta and weakly with that of PKC epsilon (By similarity). Interactswith UBE4B. Interacts with SAP30L. Interacts with SCOC and ULK1;SCOC interferes with ULK1-binding to FEZ1. Directly interacts withSCOC and UVRAG. Stabilizes the interaction between SCOC and UVRAGduring amino acid starvation. |
Post-translational modifications | Phosphorylated by protein kinase C zeta; which enhancesinteraction with UBE4B and polyubiquitination.Polyubiquitinated in a UBE4B-dependent manner; which does notlead to proteasomal degradation and may be important for neurogenicactivity. Polyubiquitin linkage seems to be mainly through Lys-26. |
Important Note | This product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications. |
Background Descriptions | Frequent loss of heterozygosity (LOH) at human chromosome 8p22-p21 is associated with various tumors including prostate and breast cancer. The 8p22-p21 region contains the FEZ1 gene, which is altered in tumors of the esophagus, prostate and breast. The FEZ1 protein (also known as leucine zipper putative tumor suppressor or LZTS1) contains a DNA-binding leucine zipper motif. FEZ1 is expressed in normal breast and prostate, but alterations in FEZ1 expression result in abnormal cell growth. The absence of FEZ1 expression is characteristic of breast and prostate cancer cell lines as well as primary breast and pro-state tumors. This absence of FEZ1 may be due to several factors, including mutations in the FEZ1 gene or hypermethylation of the CpG island flanking the FEZ1 promoter region. FEZ1 acts as a negative regulator of cell growth. During cell-cycle progression, FEZ1 localizes to microtubule components and is hyperphosphorylated by cAMP-dependent kinase. |
