# An update of the macaque testis proteome

## TL;DR

This paper updates the rhesus macaque testis proteome to improve genome annotation and understanding of spermatogenesis.

## Contribution

The study provides a refined and expanded testis proteome with evidence for predicted genes and Y chromosome proteins.

## Key findings

- 74,433 peptides corresponding to 9,247 protein groups were identified.
- The dataset supports proteogenomic annotation of the macaque genome.
- It offers insights into the mechanisms of macaque spermatogenesis.

## Abstract

The genome sequence of rhesus macaque is a draft version with many errors and is lack of Y chromosome annotation. In the present dataset, we reanalyzed the previously published macaque testis proteome. We searched for refined protein sequences, potential Y chromosome proteins and transcripts predicted proteins in addition to the latest Ensembl protein sequences of macaque. A total of 74,433 peptides corresponding to 9247 protein groups were identified, and the data are supplied in this paper. The updated version of macaque testis proteome provided evidences for predicted genes or transcripts at the peptide level. It can be used for further in-depth proteogenomic annotation of macaque genome and is useful for studying the mechanisms of macaque spermatogenesis.
