Introduction

Pfam

Est1 is a protein which recruits or activates telomerase at the site of polymerisation [1]. Structurally it resembles a TPR-like repeat.

InterPro

Est1 is directly involved in telomere replication. It associates with telomerase and, during its interaction with CDC13, telomerase activity is promoted [PUBMED:12169735, PUBMED:12454059].
