In AML cells, FBXO21 can ubiquitinate p85α, a regulatory subunit of the PI3K pathway, leading to its degradation. This reduces PI3K signaling, promotes p85α dimerization, and activates ERK, thereby influencing cell proliferation and survival. Silencing FBXO21 in AML cells induces differentiation, inhibits tumor progression, and increases sensitivity to chemotherapeutic agents. FBXO21 can regulate immune responses by ubiquitinating and degrading proteins like ASK1 through pro-inflammatory cytokine pathways. It can also ubiquitinate p85α, affecting CXCL10 expression and modulating immune cell infiltration and anti-tumor activity. In renal cell carcinoma, overexpression of FBXO21 significantly suppresses ccRCC cell proliferation and metastasis both in vitro and in vivo. It may be related to the stromal score and the infiltration levels of immune cells associated with prognosis. Additionally, FBXO21 overexpression increases the expression of key molecules in the CREB pathway.\n\u003cb\u003eSpecification\u003c\/b\u003e\nTested Reactivity: human, rat\nHost \/ Isotype: Rabbit \/ IgG\nClass: Polyclonal\nType: Antibody\nImmunogen: CatNo: Ag11882 Product name: Recombinant human FBXO21 protein Source: e coli. -derived, PGEX-4T Tag: GST Domain: 187-537 aa of BC034045 Sequence: DQLKFKGNRMDYYNALNLYMHQVLIRRTGIPISMSLLYLTIARQLGVPLEPVNFPSHFLLRWCQGAEGATLDIFDYIYIDAFGKGKQLTVKECEYLIGQHVTAALYGVVNVKKVLQRMVGNLLSLGKREGIDQSYQLLRDSLDLYLAMYPDQVQLLLLQARLYFHLGIWPEKVLDILQHIQTLDPGQHGAVGYLVQHTLEHIERKKEEVGVEVKLRSDEKHRDVCYSIGLIMKHKRYGYNCVIYGWDPTCMMGHEWIRNMNVHSLPHGHHQPFYNVLVEDGSCRYAAQENLEYNVEPQEISHPDVGRYFSEFTGTHYIPNAELEIRYPEDLEFVYETVQNIYSAKKENIDE Predict reactive species\nFull Name: F-box protein 21\nCalculated Molecular Weight: 537 aa, 63 kDa\nObserved Molecular Weight: 75 kDa\nGenBank Accession Number: BC034045\nGene Symbol: FBXO21\nGene ID (NCBI): 23014\nConjugate: Unconjugated\nForm: Liquid\nPurification Method: Antigen affinity purification\nUNIPROT ID: O94952\nStorage Buffer: PBS with 0.02% sodium azide and 50% glycerol, pH 7.3.\nStorage Conditions: Store at -20°C.
