Phrase: FET protein family | Statement: [TAF15, memberOf, FET protein family]

Target entity: FET protein family
Context triple: [TAF15, memberOf, FET protein family]

• A. F protein
  F protein is a viral fusion glycoprotein of respiratory syncytial virus that enables the virus to fuse with and enter host cells.
• B. MAFA transcription factor
  MAFA transcription factor is a beta cell–specific transcription factor that plays a key role in regulating insulin gene expression and pancreatic islet function.
• C. Tec family kinases
  Tec family kinases are a group of non-receptor tyrosine kinases involved in signaling pathways that regulate lymphocyte development, activation, and function.
• D. epidermal growth factor receptor family
  The epidermal growth factor receptor family is a group of closely related receptor tyrosine kinases (including EGFR/HER1, HER2, HER3, and HER4) that regulate cell growth, survival, and differentiation and are key targets in cancer biology and therapy.
• E. Src family kinases
  Src family kinases are a group of non-receptor tyrosine kinases that regulate key cellular processes such as proliferation, differentiation, survival, and migration, and are often implicated in cancer and immune signaling.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
