The E231 series (E231系) is a Japanese commuter electric multiple unit introduced by JR East in March 2000 as the standard Tokyo-area commuter and suburban train.
E233 series
The E233 series is a JR East commuter electric multiple unit introduced in 2006 for Tokyo-area lines like the Chuo Rapid, and Japan's most numerous train type.
E235 series
The E235 series is a stainless-steel commuter electric multiple unit built by J-TREC for JR East, introduced on Tokyo's Yamanote Line in 2015 and the Yokosuka and Sobu Rapid lines from 2020.
E2F Family
The E2F family (E2F1–E2F8) is a group of transcription factors controlling cell cycle, apoptosis, and differentiation genes, regulated by RB pocket proteins, with activator (E2F1–3a) and repressor (E2F3b–8) classes.
E2F1
E2F1 (E2F transcription factor 1, gene ID 1869) is the founding member of the E2F transcription factor family, an RB-regulated activator driving G1/S cell-cycle genes, DNA repair, and apoptosis, with dual oncogenic and tumor-suppressive roles in cancer.
E2F2
E2F2 (E2F transcription factor 2, HGNC:3114) is a human activator E2F transcription factor that binds DP proteins and pRB, controls G1/S cell cycle progression, and acts as tumor suppressor in T cell lymphoma but oncogene in ovarian cancer.
E2F3
E2F3 (E2F transcription factor 3, HGNC:3115, 6p22.3) is a human gene encoding an E2F family cell-cycle transcription factor that binds pRB and DP proteins; it produces two isoforms, growth-regulated E2F3a and constitutive E2F3b, essential for proliferation and myogenic differentiation.
E2F4
E2F4 (E2F transcription factor 4), gene at human 16q22.1, is a repressive E2F family member that binds all three RB-family pocket proteins and, in the DREAM complex with p130 and the MuvB core, represses about 1000 cell cycle genes in G0; it also regulates cilia, adipogenesis, and stem cell differentiation.
