tatbeclin 1

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 polyglutamine expansion protein aggregates and inhibits various pathogens, such as HIV-1, in laboratory experiments. Additionally, it decreases mortality in mice infected with chikungunya (CHIKV) or West Nile virus (WNV).

Tat-beclin 1 acetate is a potent inducer of autophagy and interacts with the negative regulator of autophagy, GAPR-1. Tat-beclin 1 acetate decreases the accumulation of polyglutamine expansion protein aggregates and the replication of several pathogens (including HIV-1).

Tat-beclin 1 TFA, a peptide derived from a segment of the autophagy protein beclin 1, effectively induces autophagy and interacts with the autophagy negative regulator GAPR-1 (GLIPR2). It reduces the accumulation of polyglutamine expansion protein aggregates and limits the in vitro replication of various pathogens, including HIV-1. Additionally, Tat-beclin 1 TFA has been shown to decrease mortality rates in mice infected with chikungunya (CHIKV) or West Nile virus (WNV) [1].

The compound retro-inverso TAT-Beclin 1 D-amino acid demonstrates superior activity and resistance to proteolytic degradation compared to the L-amino acid peptide when used in vivo. TAT-Beclin 1 is capable of inducing autophagy in peripheral tissues of adult mice and in the central nervous system of newborn mice.

Tat-beclin 1scrambled is the disordered segment and control of Tat-beclin 1, derived from a region of the autophagy protein beclin 1. Beclin 1 induces autophagy by interacting with HIV-1Nef and the autophagy inhibitory factor GAPR-1 (GLIPR2). Tat-beclin 1 decreases both the accumulation of polyglutamine-expanded protein aggregates and the replication of several pathogens, such as HIV. Additionally, Tat-beclin 1 reduces mortality rates in mice infected with chikungunya or West Nile virus.
