Beclin1-ATG14L interaction inhibitor 1 (com 19) 作为一种选择性抑制剂,特定抑制脂质激酶VPS34的复合物 I 中Beclin1与ATG14L的相互作用,而对Beclin 1-UVRAG作用重要的VPS34复合物 II 无影响。由此,其阻断VPS34复合物 I 形成,抑制自噬过程,但不干扰复合物 II 介导的囊泡运输。
Tat-beclin 1, a peptide derived from the autophagy protein beclin 1, is a powerful inducer of autophagy. It interacts with GAPR-1 (GLIPR2), a negative regulator of autophagy. Tat-beclin 1 effectively reduces the buildup of polyglutamine expansion protein aggregates and inhibits the replication of various pathogens, such as HIV-1, in laboratory experiments. In addition, it has demonstrated the ability to decrease mortality in mice infected with chikungunya (CHIKV) or West Nile virus (WNV).
