Protein attributes

Sequence length452 AA.
Sequence statusComplete.
Sequence processingThe displayed sequence is further processed into a mature form.
Protein existenceEvidence at protein level

General annotation (Comments)

Function

Involved in the activation cascade of caspases responsible for apoptosis execution. Might function by either activating some proteins required for cell death or inactivating proteins necessary for cell survival.

Catalytic activity

Strict requirement for an Asp residue at P1, with 316-asp being essential for proteolytic activity and has a preferred cleavage sequence of Val-Asp-Val-Ala-Asp-|-.

Subunit structure

Heterotetramer that consists of two anti-parallel arranged heterodimers, each one formed by a p18 subunit and a p12 subunit. Interacts with LRDD. Ref.12 Ref.13 Ref.15

Tissue specificity

Expressed at higher levels in the embryonic lung, liver and kidney than in the heart and brain. In adults, higher level expression is seen in the placenta, lung, kidney, and pancreas than in the heart, brain, liver and skeletal muscle.

Post-translational modification

The mature protease can process its own propeptide, but not that of other caspases.

Sequence similarities

Belongs to the peptidase C14A family.

Contains 1 CARD domain.

Sequence caution

The sequence AAA58959.1 differs from that shown. Reason: Erroneous initiation.

The sequence AAO25653.1 differs from that shown. Reason: Erroneous initiation.

The sequence AAP22346.1 differs from that shown. Reason: Erroneous initiation.

The sequence AAP22349.1 differs from that shown. Reason: Erroneous initiation.

The sequence BAD92877.1 differs from that shown. Reason: Erroneous initiation.

Binary interactions

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]

Note: Isoforms differ in the N- and C-termini.
Isoform 1 (identifier: P42575-1)

Also known as: ICH-1L;

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
Note: Acts as a positive regulator of apoptosis.
Isoform 2 (identifier: P42575-2)

Also known as: ICH-1S;

The sequence of this isoform differs from the canonical sequence as follows:
     1-31: Missing.
     323-452: DETDRGVDQQ...LYLFPGHPPT → GGAIGSLGHLLLFTAATASLAL
Note: Acts as a negative regulator of apoptosis.
