 -!- FUNCTION: Acts as component of the Sec62/63 complex which is
     involved in SRP-independent post-translational translocation
     across the endoplasmic reticulum (ER) and functions together with
     the Sec61 complex and KAR2 in a channel-forming translocon
     complex. A cycle of assembly and disassembly of Sec62/63 complex
     from SEC61 may govern the activity of the translocon. SEC63 may
     affect SEC1-polypeptide interactions by increasing the affinity of
     targeting pathways for SEC61 and/or by modifying SEC61 to allow
     more efficient polypeptide interaction. May also be involved in
     SRP-dependent cotranslational translocation. Is essential for cell
     growth and for germination. {ECO:0000269|PubMed:11226176}.
 -!- SUBUNIT: Component of the heterotetrameric Sec62/63complex
     composed of SEC62, SEC63, SEC66 and SEC72. The Sec62/63 complex
     associates with the Sec61 complex to form the Sec complex. SEC63
     interacts in its phosphorylated form with SEC62. May physically
     associate with KAR2 in the endoplasmic reticulum and this
     interaction may be regulated by ATP hydrolysis. Part of a complex
     consisting of KAR2, SEC63, SEC66 and SEC72.
