01

Overview

Ataxin-7-like protein 1 (ATXN7L1) is a protein coding gene and a paralog of ATXN7, which is a core component of the SAGA (Spt-Ada-Gcn5 acetyltransferase) chromatin remodeling complex[1][3]. ATXN7L1 shares significant amino acid homology with ATXN7 and is thought to have overlapping or compensatory functions, particularly in complex formation and chromatin regulation, although its precise molecular role is not well defined[1]. ATXN7L1, along with its paralogs, may substitute for ATXN7 or ATXN7L2 in specific stages of development or differentiation and has been implicated as a possible modulator of neurodegeneration through compensation mechanisms in models of spinocerebellar ataxia[1]. There is no current evidence that ATXN7L1 is a direct therapeutic target, and no drugs are known to interact with it[3].

02

Mechanism of action

Not applicable; no known drugs

03

Biological functions

Possible role in transcriptional regulationMay function as a component of chromatin modifying complexesPotential functional redundancy or compensation with ataxin-7, especially in the Spt-Ada-Gcn5 acetyltransferase (SAGA) complex’s deubiquitinase module[1]Possibly involved in development and cellular differentiation[1]
04

Disease associations

Neurodegenerative disease (implicated in the context of spinocerebellar ataxia 7 through paralogy and functional compensation, but direct evidence of causality is lacking)[1]Other (evidence of gene involvement in cellular proliferation and early cerebellar dysfunction in isolated cases)[1]
05

Safety considerations

None reported; functional deficiency in mouse models causes developmental defects and perinatal lethality, but there are no known therapeutic interventions targeting ATXN7L1[1]
06

Interacting drugs

None reported
07

Biomarkers

None reported
